What is Firefox?

Firefox is a free, open-source web browser for Windows, Linux and Mac OS X and is based on
the Mozilla codebase. It is small, fast and easy to use, and offers many advantages over
Internet Explorer, such as the ability to block pop-up windows.
 
What is Mozilla?

Mozilla is an open-source web browser and toolkit, designed for standards compliance,
performance and portability. The Mozilla Foundation coordinates the development and testing of
the Firefox browser by providing discussion forums, software engineering tools, releases and
bug tracking.
 
What's the difference between Firefox and Mozilla?

Mozilla (Application Suite, also known as SeaMonkey) is a complete suite of web related
applications, such as a browser, a mail/news client, a chat client and much more. Firefox is just
a browser , which makes it a better choice if you already have a mail client for example. Also,
since Firefox is smaller than the whole Mozilla suite, it's faster and easier to use.

Note, though, that Firefox is not the standalone Mozilla browser. The user interface in Firefox
differs from Mozilla in many ways.

Is Firefox more secure than Internet Explorer?

Yes, Firefox and all other Mozilla-based products are more secure. Why? Here is a list of the most
important reasons:

It is not integrated with Windows, which helps prevent viruses and hackers from causing
damage if they somehow manage to compromise Firefox.

There is no support for VBScript and ActiveX, two technologies which are the reasons for
many IE security holes.

No spyware/adware software can automatically install in Firefox just by visiting a web site.

Firefox doesn't use Microsoft's Java VM , which has a history of more flaws than other Java
VM s.

You have complete control over cookies.
 
Can Firefox coexist with Mozilla?

Yes. Firefox and the Mozilla Application Suite use different profiles that don't interfere with each
other. In Linux, however, there can be problems starting Firefox if Mozilla Application Suite is
already running.
 
What's the difference between releases and nightlies?

Releases are generally more stable versions of Firefox that should probably be downloaded by
most users. Nightly builds are released every night and contain the very latest changes, including
new features as well as new bugs. Don't expect everything to work in the nightly builds.
 
Is Firefox available in my language?

Possibly. Since Firefox is an open-source project, contributors are constantly translating Firefox
into other languages.
 
Where is the e-mail client?

Firefox is a web browser only, not a complete Internet solution. However, the Mozilla Foundation
has also produced a great mail and news client called Mozilla Thunderbird .
 
Im a Linux user, does Firefox support XFT?

Yes, official builds with XFT support are available from mozilla.org.
 
Where are my bookmarks, passwords, and other personal information saved?

Firefox stores your personal settings, such as the bookmarks, cache and web form data, in a
profile folder.
 
How do I move my profile or restore a backed up copy?

It's possible to move the location of a profile folder. This could be useful if you have a backed up
profile folder
somewhere on your hard drive and want to tell Firefox to use that as your profile.
 
What is Talkback?

If Firefox crashes, you'll see a program called Talkback appear, asking you to send information
about the crash. Asa Dotzler of mozilla.org has written a good explanation of what Talkback is:

Talkback is a client application and server (plus server infrastructure and development /
administration people) contributed to mozilla.org by Netscape. mozilla.org, many years ago,
agreed to make an exception and include this product with our binary nightly and milestone
distributions even though it's not open source because it provides huge value in debugging and
isolating stability issues. Talkback has been used to identify and debug thousands of major crash
bugs in Mozilla over the years and we're very happy to be able to include it in the Firefox testing
builds.

How it works: A Talkback binary is packaged up with the Firefox browser binary. When the
browser crashes, the Talkback application is triggered and it offers the user the option to
participate. If a user says no then nothing happens. If a user agrees to help the Mozilla effort by
submitting crash data then she is prompted with optional fields for including her e-mail address,
the URL that triggered the crash and a comment. That user-entered data along with a stacktrace
of the crash is sent to a Talkback server at Netscape which is accessible to many of the Mozilla
developers. In aggregate, all of the crash data can very quickly point out specific problems being
encountered by large groups of users. A small team of engineers pour through these aggregate
reports and turn them into bugzilla bugs with good debug information which leads to quick fixing
of the most high-profile stability problems. To see some of these bugs, query bugzilla for the
keywords topcrash and topcrash+

What else: Talkback is not spyware, adware or anything of the like. Users are clearly prompted
and asked to submit the report. User data unrelated to the Mozilla crash isn't at all useful to us.
We only care about making Mozilla more stable. If you don't want to help Mozilla and Firefox
become more stable by submitting your crash reports then don't. No data is being sent without
your explicit consent. I'd encourage anyone that wants to see this browser improve to submit
those reports. They are very, very helpful. But, like I said, if you don't want to, then don't. Just
remember that we can't fix the bugs we can't identify. If you're happy seeing the same crash
over and over then don't worry about sending in that report.
