Firefox 3.5 (formerly known as 3.1) adds support for new web standards including audio and video tags and downloadable fonts, a private browsing mode, significantly improved JavaScript performance, and more.

Not long ago Mozilla changed the release cycle of Firefox, so that major new versions (Firefox 5, 6 and so on) will be released every 2-3 months. Currently, the latest alpha release is Firefox 6 Aurora, while the latest beta development version is Firefox Beta 5, which has made it into the Firefox Next PPA already. Installing this version should be very easy if you follow the next steps.

Firefox 3.6 was released yesterday, after over six months since the last major release, version 3.5.

The latest Firefox build, Firefox 3.6.2 is released. And Ubuntuzilla Repository is the easiest way to install Firefox 3.6.2 in Ubuntu. Let's get started.

If you are running a recent distribution release, say, Ubuntu 11.04 or Linux Mint 11, you are likely running Firefox 4. But what if you want to run the bleeding edge version (of Firefox), that is the Daily Build?

Firefox 4 Beta (version 1) considered to be stable and safe to use for daily web browsing, though the features and content may change before the final product release. At this time many Add-ons may not yet have been tested by their authors to ensure that they are compatible with this release.

Firefox only (Windows/Mac/Linux): Popular Firefox extension Tab Mix Plus has finally released an update supporting Firefox 3, meaning that the tabbed browsing enhancements you'd come to know and love with TMP in Firefox 2 are now ready for your updated Firefox install

Firefox is a well known success case. I ’ve been using it for years and version 3 (which is almost ready) has great improvements. Opera has been around for years and it’s a stable browser, known for innovations in the browsing experience. So, after seeing the cool new features of Firefox, I was curious at what Opera was offering these days.

Firefox 3.5 has been released several weeks ago, but some Ubuntu 9.04 users out there may still be using the older 3.0 version. They should not expect that they will get an automatic update since this latest Firefox release will not be officially included in Ubuntu until 9.10 "Karmic Koala".
