I don�t think this post can cover a lot of the improvements made on Firefox 3 Beta 1. I guess the delays are sure worth it. Now let�s get down to the good stuff:

Fixes of 11,000 plus bugs
Change of 2 million lines of code
One-click info button to get site (ownership and identity) info
Automatically disables older insecure versions of plug-ins
Workability on Microsoft Windows Vista parental controls
Resumption of downloads
Ability to save tabs
Places bookmarking engine with Smart Places Folder for further organization of bookmarks
Browser speed increases
XPCOM Tool that reduces memory leakage
And more!
