Q: What is the difference between and

A: provides a lot of the same development tools and resources as mozdev does (including bugzilla, cvs hosting and newsgroups), but the focus of the two sites are on different things. The site is where the core Mozilla source code is developed. The projects hosted on mozdev create applications and extensions that are based on top of that source code. For example, Firefox and Thunderbird are developed by and a large number of projects on mozdev create extensions for these applications.

Q: What is a Mozilla application?

A: Mozilla is not just a web browser. It is also a framework for building cross-platform applications using Cascading Style Sheets (CSS), Javascript, the XML-based User-interface Language (XUL), and other technologies. Developers are using Mozilla to create a wide variety of extensions and applications. For more information about developing with Mozilla, read Creating Applications with Mozilla or Rapid Application Development with Mozilla.

Q: I have a comment or question about a specific project. Where should I send my message?

If you have questions about a project hosted on mozdev, we recommend that you contact the project owner directly or post to the project's mailing list. Check the project's site for any relevant contact information.

Q: How do I start a new project?

A: Anyone is welcome to start a new project on the site. There are only a few requirements for new projects. Projects must be related to Mozilla in some way (for general purpose application hosting, try starting a project at SourceForge or Savannah). We also ask that people provide us their full name and read our Terms of Use and Copyright Policy documents. To start a new project just fill out the Start New Project form. One of the mozdev admins will follow up with you with information about how to start editing and updating your new project.

Q: Why is it taking so long to get my project set up?

A: It can take up to a week before you get a response about your new project. We receive a large volume of project requests and it takes time to sort through them all and get new projects created. We apologize for the delay and appreciate your patience. If you want to check on the status of a request, you are welcome to contact us.

Q: Why isn't my project on the active projects list?

A: All new projects start out showing up on the Active Projects list. Any project that hasn't had any CVS activity within the last 60 days are moved off the list to the Inactive or Abandoned projects list. To get your project back on the active list just update your project's CVS repository and your project should be listed as active again within 24 hours.

Q: How do I get commit access to one of the projects hosted on mozdev?

A: If you are interested in helping with the development of one of the projects hosted on this site, contact one of the developers of that project and ask them if you can become a contributor. To get access, the owner of the project needs to contact the site admins who will set up an account for you.

Q: How do I get access to add or edit bugs in bugzilla?

A: New user accounts in bugzilla are not able to edit bugs. Please contact us to have your permissions changed. For new projects, bugzilla is only added if it was requested on the new project form. For projects without bugzilla, send us an email with a list of components you'd like to use to track bugs and we'll get you set up.

Q: How do I get access to the newgroups?

A: In an effort to deal with spam, authentication is required to access the newsgroups. The global username and password to log in to any of the newsgroups is -- mozdev/maduser.

Q: What can I do to cut down on the amount of spam on my project's mailing list?

A: Unfortunately spammers target some of the mailing lists on mozdev with a lot of unwanted email. It isn't possible to completely eliminate spam, but we have created a set of tips that should make managing your list easier.

Q: I've posted a message to one of the project mailing lists and now my email address is publically viewable. Can I have my address removed or have it obscured so that spammers can't harvest my email?

A: This is an open source site and the data and information hosted here is publically accessible by design. Anonymous messages (or posts that have been edited to be made anonymous) are against the spirit of open source. If you have something that you are offering for others to read, you should be willing to attach your name to it, and to give people the ability to reply to you privately about it, in case they feel that a public reply would be inappropriate. If you want to avoid spam, use mail filters, or don't post. (Part of this text has been taken from's Community Page.)
