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.

"This week Mozilla released the first beta of Firefox 3. Originally scheduled for mid July, the delay responds to the very long list of features this new version brings. Eight alphas and an estimated 14 months under development are both firsts for a Firefox upgrade but again are necessary for the amount of improvements and new features Firefox 3 will bring..."

Firefox 3 developers are taking all the time that they need to accomplish their new Firefox. After the Beta 1 Mozilla has released Firefox 3 beta 2 to get more feedbacks about bugs from its testing community. Bugzilla was a little bit busy lately since the beta 1 thousands of bugs fortunately 900 of them are fixed. Firefox developers are trying to reveal more bugs to make their Firefox 3 better. The Beta 2 features are very promising and the Firefox 3 will definitely beat all competitors.

Today Mozilla released the third beta for the next major Firefox update, version 3.1. Firefox 3.1, which will likely be re-numbered to Firefox 3.5, will have one more beta before the final release this summer.

Firefox 3.1 Beta 3 is done and beta 4 is slated to be released on April 14. That’s the latest from the Mozilla Firefox team, which held its weekly meeting on Tuesday.

I was telling you about my issues with scrolling in Firefox (see #6). Well, I didn't manage to fix that for Firefox 3.5 but instead, I installed Firefox 3.6 beta 1 pre (Namoroka) and the scrolling now works perfectly (thanks to Tinhed for the tip!). Also, basically everything feels a lot faster, at least in Ubuntu. This is why I suggest you upgrade to Firefox 3.6.

Mozilla has recently released the fourth beta of the Firefox 4 browser. I have been testing it since the first beta and I am happy to see the progress and the addition of new features with each beta.

... this Firefox version, carries the code name "Namoroka" Alpha 1, and it is also currently referred to as Firefox.next. And like other Firefox Alphas, it does not bare the Firefox logo. This release uses the Gecko 1.9.2 engine and will likely include several interface improvements in later versions, such as new graphical tab-switching behavior, which was removed from 3.5 with Beta 2.

Although Firefox 3.5 (formerly Firefox 3.1) is still in beta, Mozilla is already developing Firefox 3.6 code-named Namoroka. Slated for an early-to-mid 2010 release, the browser will be marketed as Firefox.next (FX) moniker in a nod to new technologies set to take Firefox to the next level.
