What Is

Mozilla's Mission Statement

Our mission is to ensure the Internet is a global public resource, open and accessible to all. An Internet that truly puts people first, where individuals can shape their own experience and are empowered, safe and independent.

Is This Your Company?

Do You Work At Mozilla?

What is it like to work at Mozilla

How is the pay considering Mozilla is non-profit? Do you guys get bonuses? Is Mozilla generally a full-time job or just a side project that you contribute to?

I'm the only community contributor listed on this AMA. Everyone else you see on the list are full-time Mozilla employees.
January 21, 2012 on Reddit

I've always been interested in the governance of the Mozilla Foundation. Is the Mozilla Foundation board elected? Are they accountable to anyone but themselves? And given the Mozilla Foundation openly ask for donations.. can you justify the more than $500,000/year the CEO and CTO earn?[1]( [2](

I've wondered about it myself, but I understand that even though non-profits shouldn't be greedy, we need to pay competitive salaries to attract and retain whatever personnel are going to advance our mission the most. IIRC, there are rules governing how much non-profit employees can make - i.e., can't pay exorbitant wages.

How did you get involved with Mozilla to begin with? Mostly volunteers, then applied for jobs, or just happened to see that Mozilla was hiring?

I used Firefox for years and just happened to see that Mozilla was hiring. But I know we've hired a number of contributors.
January 21, 2012 on Reddit

How did you get into this line of work to begin with?

Accidentally. I hacked on web stuff as a kid, I thought I'd go to college and get a job in programming... Web development wasn't really a field. Then that changed when Paypal (the small startup back then), Trinity and other companies started yanking people from my school with huge offers and whatnot. I'm glad I stuck to doing what I enjoyed.

whenever i go back to school and finish my computer science degree, can you get me a job with mozilla? :]

Honestly, a good on-ramp to a job with Mozilla is to [become a contributor]( first!
January 21, 2012 on Reddit

How did you get into web development? How did you learn? How much of your job is design and how much is actually writing the page?

I wanted a web page, and so I kept viewing source and reading things on the web. My career has shifted more and more into the backend which ultimately is in charge of writing the page. It's software engineering more than web development.

Are you hiring interns?

Yes, always!

A couple personal questions for each of you guys. * What was your unique road that shaped you on your way to working for Mozilla? * What languages did you start with, what did you become proficient with? * Was there any project you worked on in your early years (before Zilla) that really stood out? Why? * What would you consider your best accomplishment to date while working for Mozilla? * What has been your biggest disappointment/failure/letdown (either project or expectations) while working for Mozilla? * What's one project or idea you want Mozilla to focus on next, that you guys haven't discussed as a group before? Thanks a bunch for doing this guys.

> What was your unique road that shaped you on your way to working for Mozilla? That's a long story. Tl;dr - I had a job, I didn't like it very much, I applied at Mozilla. Slightly longer, I was a tinkerer on the web since the late 90s. I like solving problems I'll have to solve again, so I ended up working on my own frameworks in PHP, and then building apps on them that solve my own problems. That created a portfolio I was eventually able to use to get jobs. > What languages did you start with, what did you become proficient with? Perl and JavaScript, together. I haven't written non-trivial Perl in 10 years and am pretty happy about that. Then PHP, and now Python. I've also dabbled in Java, Ruby, and C. I swear some day I'll get good at C. And I want to learn Erlang! > Was there any project you worked on in your early years (before Zilla) that really stood out? Why? It's always the one you least expect. I built [TodaysMeet]( to help my father teach a class. It was recently mentioned in the NYTimes and this week on RWW. I think it fills an important niche for educators. > What would you consider your best accomplishment to date while working for Mozilla? I think, personally, I'm proudest of the team we were able to build. We've more than doubled in size since I started and the average level of awesome has only gone up. I'm particularly proud of the support team, since I had the most involvement there. > What has been your biggest disappointment/failure/letdown (either project or expectations) while working for Mozilla? I really wanted to see Alex Limi's new concepts for bookmarks make it into Firefox, but I think they've been shelved. > What's one project or idea you want Mozilla to focus on next, that you guys haven't discussed as a group before? I'd like us to get more into education. There was recently a piece about the Hackasaurus project in The Atlantic, and it's a fantastic idea. Too many people are just consumers of the web. Part of our mission is creating opportunity and that means helping people become producers. Codeyear is awesome--I wonder why it wasn't our idea?

Is your software team (C, C++) hiring?


Hello Team Mozilla. I'd be interested in your QA process. I'm the manager of a the SQA team for a start up and we love FF. These rapid releases seem to me, like they would do a number of the stress levels of your SQA team so I'd be interested to know more about what they do to keep up. Best practices, test tool choices, load/performance nightmares, etc. Is there a blog or do you guys collaborate internally? Also, how far in advance do you publish release note for other developers to anticipate build changes? Thanks for any input and keep up the good work!

I can only speak to our Web QA group, not the Firefox QA group, so this may or may not be interesting for you. We do even more rapid releases than Firefox, though, with lots of sites releasing updates every week or even faster. We've had to take a look at the philosophy of QA for really rapid releases. QA now focuses a lot on automation and exploratory (manual) testing of new features--which happens in our production environments behind feature flags. For us, as web developers and web QA, the choice of tool is most frequently Selenium, since it can do things within the browser and test integration in a way that Python unit/integration tests and JavaScript unit tests can't. We also use httplib/requests and unittest, and other tools when they make sense. The key is to avoid getting too tied to one tool, and focus on what it is you're trying to assure. Then just pick the best tool for that job. That means we try to keep as much as we can in our web apps Python and JS test suites, and use integration tests, like Selenium tests, for bigger things. We don't do a lot of proactive load testing, since we do a lot of real-time monitoring in production. That's so much more valuable, as long as you have the ability to respond quickly, either with patches, or feature flags, or something. We could definitely do a better job blogging about testing.

personally I want to ask you about the very beggining of your carrer in Mozilla. What did you do before? Did you get a higher education in web-dev? or you just tallanted? How was the very begining of your work? Do you fell happy after all? I'm a "newbie" software developer, working\studing and trying to apply my self. What would be your suggestion in this case? ( may be something motivational?) Thank you in advance for your time

"Very beginning of your career in Mozilla" As a community member, I was excited about Firefox in 2004, and working professionally as an e-commerce web developer at RealNetworks. As an employee, I left to join Mozilla full time in 2008. As a web developer in general, I taught myself HTML in 1997. I had no background in computers. Education, talent, etc - If you like to play with the web and make things, keep doing it! Do it all the time! Make lots of experiments. See how cool sites work and take them apart. You can contribute to Mozilla today. Use github to learn and share. Everyone's career path is different. There is no special entitlement (school, family, wealth) needed to help change the world. The web is open and ready for your ideas.

Is there a Mozilla dev team in Germany? I am a researcher in interactive technology, and I'd like to work for a not-for-profit or open source team. Thanks!

We have some paid-staff working from Germany. We have some contributors in Germany. They all work from home right now but we're looking for a place to open a Mozilla Space in Berlin this year. [Submit your resume](
January 21, 2012 on Reddit

Is it possible at all to get a job at mozilla without an academic education?

Yes (I have only completed 1 year of university, and there are other people at Mozilla that have not completed post-secondary education), but you had better be able to demonstrate that you have the skills. In the context of the web development roles, some of the people here have answered that what you have done is going to be more valuable than what you have studied.
January 21, 2012 on Reddit

What keeps you motivated to do what you do? I know some people in the industry that seem to be driven by money/promotions, but clearly you're in a class of your own. What gets you up in the morning and pumped for your day?

For me personally, Mozilla is the first company I've worked for that has a mission I totally agree with. I love the web, and I love being somewhere devoted to the open web. If I ever left my job here, I'd probably keep working on Mozilla things in my spare time - and there are a number of people who've done just that. And, in terms of promotions at least, we seem to have a tradition of promoting people after they've already been doing the job for long enough that the promotion is an afterthought. That might sound cruddy, but what it really means is that people here generally gravitate toward what they want to do and what they're good at doing, and they do it. That kind of career flexibility makes me very happy, and I anticipate staying happy.

Not really a web dev specific question but how does the hierarchy work? You guys get your work/code verified by a leader of sorts? or do you just push it out as soon as it's done? Does mozilla cap your ideas? Or do they allow for some extreme ideas?

"Hierarchy" is an interesting question. Mozilla has it's Module Owner system, but within webdev we sort of do our own thing. We work with a number of different groups on different projects, and they become stakeholders as well as the community, us, our IT folks, QA, etc. Decisions are made on most projects with consensus from those groups. If you have an idea, no matter how crazy, and you build consensus around it, it can happen. A lot of those ideas come from community members who aren't employees, too. In terms of "how" stuff, like "how do we implement this?" We try to push decisions down as close to the people making them as possible. We have a couple of layers of hierarchy but I like to think of an inverted traditional structure. As a manager, I'm not here to tell my employees what to do. They know what to do, I'm here to help them do it, and grow as engineers and, hopefully, as people along the way.
January 21, 2012 on Reddit

First of all, thanks a ton for all the hard work and helping move the web forward. I am a big fan of Firebug and use it A LOT! My question - What's a typical day like at Mozilla? How do you guys keep yourself so motivated? What's been your favorite/most challenging project? EDIT - Thanks for

I contribute to Mozilla Webdev in my free time. So every evening I spend a few hours catching up my bug mail and figure out what to do for that evening. It may be continuing to work on a branch that I've been working on, getting a quick code review from a fellow webdev, talking to the product manager to clear up confusions, and there's always the general chatter in the #webdev channel on Mozilla's IRC network. Sometimes, I participate in Mozilla meetings when they're at a reasonable time (yeah, timezones suck). Overall, I've found it very rewarding to be a contributor and to be counted as a team member even though I'm not a paid employee. One of the most challenging bits I took up was speaking at a recent Mozilla event that I was invited. I sick for the few days preceding the event and nervous with stage fright. Eventually, though, managed to pull it off!

How many of you work remote - and do you think that it makes the job easier/harder?

Mozilla is a very, very remote-friendly company in general, and our team is (I think) remote as a majority. Personally, I'm hooked on it and would have a hard time going back to an office, now. IMO, the "easier" part is being able to work without outside interruptions, but the "harder" part is being self-motivated enough to work without interrupting yourself. My home office is mere steps away from a fully-stocked entertainment center with an Xbox. Of course, the office in Mountain View has that, too, but at least there my co-workers can see me slacking off :) There's also the issue of communications - but we attack that problem with documentation, IRC, IM, VoIP, video chat, and whatever else we can come up with. That's actually a good thing to attack, too, because we make Open Source software. Barely any contributors from the community have the advantage of being present in a Mozilla office, so being remote helps to keep Mozilla employees on the same level with non-employee contributors because most of the communication tech we use is not exclusive to the company. (For instance, did you know that our weekly all-company meeting is a public conference call? [Every week](

How does a web developer get their funding? Who pays the bills for Mozilla and and why do they pay it?

Mozilla pays its own bills. As to how Mozilla makes money, [refer to this previous question]( As web developers, we receive a salary basically like any other employee at any other company.

Hi guys. As an aspiring front end developer with no formal training, I was wondering how many of you (if any) didn't start out with a degree in comp sci or the like.

I started on GeoCities, and have no formal training at all. (My degree is in Math, which sounds related, but I consciously avoided all the useful, applied mathematics.) I started building web apps because it was fun. And after a while, bigger web apps, frameworks, stuff to solve my own problems. Then I got a job doing those things, and some freelance work, then another job, etc. When I interview someone, I don't care what their formal education is, I care if they're talented, and what they've already done.

Are you looking for Web Devs or up-and-coming Developer Advocates?

January 20, 2012 on Reddit

What do you see as "the future of the web" - say, 5 or 10 years from now (which is an eternity in Internet terms)?

I'd love to see Web Technologies used everywhere. Not only on "the web" but in every object that has a chip. I'd also love to see how IPv6 and symmetric connections will help decentralise the content. Instead of putting our data on a few webistes, we'll keep it on devices we own and applications will pull them. I recommend looking at this video by Scott Jenson : [What's an app anyway?]( It talks about how web apps can be much more powerful than native apps and that we'll have more and more Just-In-Time apps.

What's your deployment strategy ? What do you test in your codebase and how ?

**Testing** - To add to what Fred said, we also use [jstestnet]( (kumar303 wrote it) to include our [QUnit]( (JavaScript/front-end unit tests) in our CI results. Our WebQA and Automation teams are big contributors to and consumers of the [Selenium]( test automation project. We're working to get those tests included with the nose/QUnit results, because a failure is a failure is a failure, no matter where it failed. We also have developed a culture of testing--this is something I've been meaning to write a blog post about. That means a few things: 1. Time to write tests is included in how long it takes to write the code under test. A feature isn't complete without tests. 1. If you break the tests, there's some good-natured teasing, and you lose points in the CI game. Light social pressure is incredibly helpful. 1. If you break the tests, your *first* priority is fixing them. Next I want to develop a culture of performance. **Deployment** - This is my favorite topic! I've been giving talks on it for around a year now. I actually started putting a joke about that into my talks about it. My goal with all the projects I touch is to deploy continuously. Not only does continuous deployment mean fixes get to users as fast as possible, but it has a bunch of requirements that are great in-and-of themselves, like... 1. You *must* have a robust, automated, and fast deployment pipeline. One-button and wait. 1. You *must* have a high confidence level from automated tests so you don't break things. 1. You *must* have active, [real-time monitoring]( of the site. 1. You *must* keep master/trunk/whatever branch in a clean, working state, all the time. 1. Developers *must* develop a sense of ownership over their code that lasts all the way out the door. It also has a number of side benefits, like not doing code pushes at night when people are tired, or about to leave for the day. Some projects are closer than others. We learned a lot from [Etsy]( (link to blog post and [video](, watch Kellan and Erik's sections). But their [Deployinator]( tool is Ruby, and it took them a while to open source it, so we built [Chief]( to do the same thing (run some shell scripts, print a bunch of output). We've got push-button production deploys with Chief or other, ad-hoc tools, for a few sites now. We've got it set up in the -stage environment Fred mentioned for a few more. We use another tool called [Freddo]( to deploy -dev environments on Github post-push hooks. My goal is to have all new environments set up with Freddo and Chief by default in the future.
January 20, 2012 on Reddit

What are your tips on getting work in the Software Engineering/Web Development industry?

Contribute to open source projects. I met many of my friends through working together on projects and found two of the jobs I've had that way. Plus if you're contributing, your code is out there in public and you can point to it on your resume and some companies really value that in their hiring process.
January 20, 2012 on Reddit

Can you use "Bronco" as the code name for the next big Firefox release?

Haha, no. However, our [web projects]( routinely have code names as well. Our rewrite of the careers website (not live yet) is called "lumbergh", Mozilla Add-ons' codebase is called "Zamboni", our newsletter signup library is called "basket", and so on. So, we could consider calling a project "bronco". What kind of project would it be? :)

What is the policy for the web dev team for hiring. Do you guys people from other countries? The thing is, I love mozilla and I'm always following your steps and posts, but I'm from Brazil. I didnt started submiting patches and so because Im having a ton o work lately (one has to eat x_x) . But I have a true interest on joining mozilla as a contributor, and maybe a employee. Can you guys give a hint on how is the process to getting job at mozilla

If I'm not mistaken, we have people in the US, Canada, England, France, South Africa, India, Indonesia and one of us is gonna work from Thailand this week. In terms of nationalities, we are American, Canadian, British, French, German, South African, Swedish, Indian, Australian. I might miss some nationalities. Some people work from of our [9 (current) offices](, others work from home or cafe or pubs. I personnally pushed a commit from a train between Paris and Amsterdam. I know others pushed a commit from a plane. And one of us wants to push a commit from a bike.

How does Mozilla make money - really - and pays for your salaries ? * edit: for clarity, I just mean how does Mozilla make enough money to actually keep alive large teams of motivated people ?

The [State of Mozilla Annual report]( answers this question very nicely. The report also gives actual numbers for 2010. >The majority of Mozillas revenue is generated from search functionality included in our Firefox product through all major search partners including Google, Bing, Yahoo, Yandex, Amazon, Ebay and others. Mozillas reported revenues also include very important individual and corporate donations and grants as well as other forms of income from our investable assets.

Cannot talk specifics but, suffice it to say Mozilla pays well

What should an upcoming Mozilla webdev intern know before coming in?

This question implies that you have already been accepted as an intern (correct me if I'm wrong), so that would assume you have shown that you can work in a team, are interested in the things we are doing, and that have written some relevant code. If you want to get a head start on the code side, familiarize yourself with Python and Django, as well as HTML / CSS and JavaScript. You will, however, get plenty of code reviews and advice, so don't panic :) You are also welcome to pick any Mozilla website you find interesting and take a look at its code, ask questions, maybe even file a bug or submit a patch. Also, go ahead and find us on IRC ( for instructions, channel #webdev) and say hi! Looking forward to meeting you soon :)

I'm probably too late but what did you study at university specifically to get onto your current job? Computer Science with a mix of Computer Security later on?

Bachelor of Science in Microbiology, minor in chemistry Master of Science in Management Information Systems

What kind of qualifications would I need to come work with you awesome guys?

I'm not sure if there is any formal qualification *required* but a CS degree is probably helpful. Of course if you demonstrate your skill otherwise (e.g. write software that finds lots of flaws in our code or start working on our code and doing an awesome job there), then the chances are good to be taken as an intern or employee.

What can a student like me do to get an internship with you guys, either for 2012 or upcoming years? (Note: I applied through Jobvite, but in my haste, I did not type a cover letter, and I was declined (probably for more reasons than one). Even as I gain more experience from my degree program and activities, I can't reapply for the same position. Is there anything I can do?

Participate. Mozilla is a very open company for this sort of work. See the other threads about contributing. If you have a coding related project, Mozilla has been a participant in every [Google Summer of Code]( so far. Member orgs are announced in January or February. For previous GSoC info see and play with the year.

A slightly personal question. How did you all end up working for Mozilla i.e. were you all interested in computer science and security from a young age or did you enter the field serendipitously?

Long career in security found a job posting on the Mozilla web site, applied and got it. I have been involved in security/computers for 31 years.

Do you think any of your colleagues are former hackers? Seems like the perfect background for security

We certainly *think like* attackers. When we go through airport security, we have to be careful not to talk about how easy it would be to bypass their rules or create havoc. I don't know if my colleagues have *been* attackers, but I wouldn't be surprised if they have. When I was in high school, I pulled off some IRC-related attacks, such as MITMing sex chat participants and writing an mIRC script.ini virus.

1. To the security guys, does working in this field of work all day take away from the enjoyment of it? 2. How are issues in the Mozilla Bug Bounty program ( ultimately determined? (paid/not paid) 3. Have there been ANY breaches into Mozilla's servers at all? If not would you actually tell us if there had been? 4. Is Mozilla collaborating with government/private sectors to ensure their browsing experience is a secure/safe one more so than the average user? 5. What're some of the questions you ask in an interview for a new hire? Also It's really great you guys are willing to do this and it should really speak to the openness of Mozilla for those of us who are/were skeptical.

1) Not for me, I love the challenge 2) There is a group that meets to determine that given the published critera. 3) If there had we would have made it public had it impacted sensitive user data (I think, I am not infrasec). As that is just the way we roll. 4) Not that I am aware of, we think every user regardless of who they are or work for should have the safest experience we can provide. 5) Really varies, I am a PM so I focus on PM types skills, how a person thinks and reacts to situations and people. Can they think like an attacker to find security issues, that kind of stuff. You're welcome, we share what we can without putting users at risk.

I'm not the most technically minded, so this is going to be in pretty basic terms, but has anything ever cropped up that has just been completely devastating? As in has anything happened that is just "oh holy *** we're in trouble now!"? Perhaps this is a daily occurrence? (I really don't know enough about anything like this)

Not in my experience, we generally are prepared for things and expect things to go wrong at some point. That is the nature of security, the attackers generally have the advantage over defenders. As such we prepare contingencies, and contingencies for contingencies in some cases. And my job especially is to try and build a process that finds them and fixes them before we ship them so they never become huge problems.

if i have 2 college degrees, but neither are tech related, whats the best way to land a decent job in IT or tech field?

Launch a startup, thats what all the cool kids are doing! (j/k) Really though, my experience has been that the deciding factor in finding a good tech job are the following: - Experience; proof that you can do what you say you can - Communication; the ability to explain yourself, your achievements, and your ideas, and the ability to sell yourself which is critical to get buy-in for your ideas, especially if they are disruptive to the business/industry - Cooperation; the ability to play well with others. Not just collaboration, but the ability to promote yourself, your team, and turn opportunities for personal success into win-win situations for everyone involved Other than that, hard work :)

Are you required to sign an agreement stating you will not use any other browser except Firefox? My brother has worked for various bottling companies (Both beer and soft drink) and if he was caught drinking a competitor's product, he could be fired on the spot. Thanks for your time.

That is so not an issue. Virtually everyone at Mozilla uses a range of browsers, for a variety of reasons. Firefox is our flagship product, but Mozilla's mission is about promoting the Open Web, saying only use our product is not consistent with that!
December 22, 2011 on Reddit

1. Whats the hierarchy of the tech team there? How many groups and which group is the largest team strengthwise? 2. Who decides, and how, what features/bugs take priority and what doesn't.. essentially what is the culture/decision process?

1. The hierarchy that exists is largely there for management purposes. The organization is run as a meritocracy; it doesn't matter if you are a day 1 new hire, if you have a good idea, you are encouraged to voice it! As an organization one of our important values is the ability to communicate openly and honestly about the challenges we face as an organization, and in the products we build. For individual projects teams are highly dynamic, and we bring in the resources that are required from other teams. 2. Although we have product owners and leads, the community (both employees and contributors) and our users inform the decisions that are made about bugs and features.

What were you doing before joining the Mozilla infrastructure? Can you describe the best part of the job? The most stressful parts? What would you suggest for people to protect their online information while browsing that you are surprised most people do not do? Who is watching my internet activity? Can you tell me your favorite ice cream flavor? Many thanks for answering.

I worked for a very large financial institution. The most stressful part is deciding to work from the office or from home... today I chose to work from home for the morning... now I have to decide wether or not to keep answering questions, or head to our office for a team lunch! (Hint: to keep me answering questions, upvote this!) TYPE HTTP**S** Several departments of the US Department of Homeland Security, your ISP, anyone interested enough to sniff your traffic, and if you are in a coffee shop, that skeevy looking person in the corner. Did you forget to connect with a VPN? Mint Chocolate Chip Your welcome!

1) What is it like working at Mozilla 2) What is the biggest security risk you've ever had? 3) What is the weirdist security breach you've had, if you have even had one. Thanks!

1) So awesome... The work we do is really cool (we get to play with all the new technologies), we can talk about the work we do (we are actually challenged by the amount of content to review to make public since opening stuff up takes time away from securing stuff!), and we get to support open technologies. The thing that makes Mozilla such a great place to work is the community. Every time I sit down and talk with people at a Mozilla office (in Mountain View, San Francisco, or here in Vancouver), I always come away feeling like I have learned something or have some inspiration for some new project. 2) The biggest concern we have related to risk is the impact our decisions have on our users. Whether that risk is to privacy, the integrity of the systems that host our user data and the systems that distribute our products to end users, or the integrity and security of our users devices, every security and privacy decision we make is made in consideration of the users. 3) Nothing too unusual here at Mozilla. I have found bugs in access control software that allows me to open and close doors on buildings, which was cool :D

do you have a dog to tour the facility? what kind of training do you have (sport, self defense?)? do you wear a weapon for this security job?

On the front lines of cyber space our minds are the weapon.. or something like that...

(Made an account just to ask these questions) -I'm a current student in Penn State's SRA cybersecurity and cyberterrorism Major 1. What would you say you are looking for most for new applicants? 2. What should I gear my studies to so I'm able to enter the field efficiently?

When I interview candidates (which is often, because we are always growing!, shameless plug: ), I look for the depth of technical knowledge, the ability to communicate effectively, and the ability to adapt quickly. In addition to those things, a candidate needs to be "a good fit"; they have to have values and ideals that are consistent with the core Mozilla mission, or be open to adopting those ideals. In particular, for technical skills, it is critical to be able to explain how multiple vulnerability classes work, and not just the common cases. Being able to explain modern security challenges or newer browser/server/operating system security controls and weaknesses is valuable too. Not at the expense of building a solid technical base, but you really, really need to understand risk management. I refer to my time in the finance sector as a technical backwater, but the risk management skills and focus that I picked up there was very valuable to me, and is something that is not always easy for people to learn. Being able to go beyond the typical ALE style risk equations and understand the role of threats to the business helps alot. EDIT: Reddit, why u no like numbered lists?

What's your view on the new release schedule? The numbers don't really matter, but for a non-poweruser it might get confusing why there's a new one every 6 weeks.

The rapid release cycle is confusing for some users, but the biggest reason for that is most likely the need for intervention during an upgrade. Some time very soon we will provide a silent update feature that will remove many of those headaches for non-technical users. As for the release cycle, it makes some aspects easier; since we have regular feature freezes and we know that a new release is coming soon we can a) focus effort on features that are going to ship in the next couple of releases, and b) hold a feature back for a release if there are security (or other) concerns since we know that there will be another release soon. It takes some adjustment, but it really is better for our users since it allows us to focus on improving the quality and feature set of Firefox in discrete steps instead of monolithic upgrades.

1) What is the most mind boggling problem you've encountered over the years? 2) Do you personally use Firefox as your browser? 3) Did the Mozilla team get a cake from Microsoft for the release of 9?

1) Securing passwords in a user friendly way. Doesn't matter if it is in government, finance, or even in a technical community. Password management (including generation and storage of credentials) is very challenging due to the human element. 2) Yep. I have profiles for Firefox, Aurora, and Nightly, each one with its own set of plugins. I also use Chrome, Safari, and every version of IE back to 6 since I need to verify if bugs in web applications are exploitable in these products. 3) I am based in Vancouver, so I am not 100% sure, let me find out!
