Mozilla launches Firefox 3 RC2
So what's new with Firefox 3 RC2? Not a whole heck of a lot that you'll notice. This release wasn't about adding new features, but rather fixing bugs. There's still a rather lengthy list of known issues which you can read about in the release notes.
Also, keep in mind that installing Firefox 3 RC 2 will overwrite your previous Firefox installation. You shouldn't lose any bookmarks or preferences, but some add-ons may stop working until the developers update those extensions.
