"Mozilla has announced the official release of the third Firefox 3 beta, which includes many user interface improvements and a handful of new features. Firefox 3 is rapidly approaching completion, and much of the work that remains to be done is primarily in the category of fit and finish. There will likely only be one more beta release after this one before Mozilla begins issuing final release candidates.
The bookmark dialog, which was integrated into the URL bar in beta 1, has been further tweaked to improve usability. The Delete button at the bottom of the dialog has been replaced with a Cancel button. A Remove Bookmark button now appears at the top of the dialog underneath a label which states the that page has been bookmarked." – Content courtesy of First look: Firefox 3 beta 3 polishes rough edges
