The Mozilla developers have released a total of three beta versions of the upcoming web browser Firefox 3.6 in November so far. The latest version Firefox 3.6 Beta 4 was just released and is now available for download at the official Mozilla website and through the “check for updates” option in the Firefox web browser itself.
The new version of Firefox fixes 140 bugs of which two have been rated as blocker and 21 as critical. It is therefor recommended for Firefox 3.6 beta users to update their web browser as soon as possible to fix the bugs and make the web browser more stable. Most of the bugs – if not all – seem to be stability bug fixes that fix possible crashes that can happen under certain circumstances in the older beta versions.

Firefox users who are interested in all the fixes in this new version can check out the detailed bug lists over at Bugzilla. About a quarter of the installed add-ons were not compatible on our test system including popular add-ons like Greasemonkey. It was however no problem to force compatibility with the Nightly Tester Tools add-on.
The Mozilla Firefox beta page lists downloads for all supported operating systems and languages.

Is it just me or did the tab behaviour change from beta 3 to beta 4?
it opens a new tab to the far right now, instead of directly next to the current tab. How can I change that without add-ons?
I do not think there is a way. It was my understanding that all betas of Firefox 3.6 used that tab behavior.
You need to type about:config in the address bar (and press [Enter]). Then, look for the option browser.tabs.insertRelatedAfterCurrent and change its value.
Done :)
insertRelatedAfterCurrent works perfectly fine – thanks.
Do you know what the “Related” part means? Probalby not all tabs are treated the same way… Tried to google but strangely nothing useful found.
