Mozilla Firefox 3 Beta 1 Release Notes

Firefox have launched this beta version to the wider community with the express purpose of having it tested. If your a browser tragic then get involved, but be warned, your extensions wont work. Out of the 30 odd extensions I have installed only Dom Inspector and Add New Tab worked.

This version integrates the Gecko 1.9 rendering engine and the rewrite of code is extensive. My first impressions is that its UI changes are subtle and the speed improvements are very noticeable

Installation:
I simply installed it in it’s own folder and am having no problems running this and Firefox 2.0.0.9 on my Mac.
It picked up my profile and bookmarks just fine. There is also a new Mac specific skin, which may excite some but I find too dark.

Bookmarking sees huge improvements. One example is Tags, where you can associate keywords with your bookmarks to sort them by topic

Firefox 3 Beta 1 is a developer preview release of Mozilla’s next generation Firefox browser and is being made available for testing purposes only

Important:

Over 300 individual memory leaks have been plugged, and a new XPCOM cycle collector completely eliminates many more. Developers are continuing to work on optimizing memory use (by releasing cached objects more quickly) and reducing fragmentation.
