Mozilla has unofficially released the Firefox 3.5 Release Candidate, and has unofficially stated that Firefox 3.5 final will become available by the end of the month. Mozilla Firefox 3.5 RC1 has been seeded for download, although it wasn’t expected to go live until June 19. Well, you can download it right away, play around with it, see what’s new, and anxiously wait for the final release to become available in the following days.

According to the Mozilla Foundation, the new Firefox 3.5 will be packed with 5,000 new features like built-in video, offline web-apps local storage, private browsing (like Google Chrome’s), geo-location, About Me, stability enhancements, speed improvements, and plenty bug fixes.

Now that Firefox 3.5 is very near, Mozilla is thinking about upcoming versions which will feature the process isolation feature. This is another feature imported from Google Chrome and it means that if one browser tab crashes, the rest of the tabs will remain intact and the browser will not crash. The successor of the Mozilla Firefox 3.5 has been codenamed Namoroka and it will also feature a 64-bit Mac OS X version.

Microsoft with its Internet Explorer is losing ground to Mozilla Firefox and Google Chrome, but we shouldn’t forget the Opera has lost a lot. Things are about to change as Opera Unite is here, Chrome is growing fast, Firefox is improving fast, IE will not ship Windows & Europe version, and I think the remainder of 2009 will be very interesting in the browsers war.
