Firefox 3 Beta 2 is released!
By Al Jigong Billings
Notable improvements are all over the place but especially in the Awesome Bar and Places (the updated Bookmark and History system), where the organizer has been improved along with the "smart" folders that query the database backend. You can take a look at the API documentation for Places if you want more information. You can also see the overall UI plan for it, if you're so inclined. I think Places is one of the great things in this release but then I do some of the QA for it so I am biased.
Mozilla Links has been posting on Firefox 3 on a regular basis and I expect that there will be more posted there for this Beta 2 release.
You can download Beta 2 on the beta download page.
