I installed the Mozilla Firefox 3 (Release Candidate) and then I started to notice that many of my favorite Add-ons are still incompatible with Firefox 3. And worse, I can’t erase my browsing history at all. Well, I can’t blame the Mozilla team, Firefox 3 is still on its pre-release (bugsy bugs) version. Perhaps I should wait until they release the official version.

So I think I will reinstall my good ol’ Mozilla Firefox 2 and then I’ll wait for the Download Day to reinstall Mozilla Firefox 3

Anyway, these are the Add-ons I can’t live without (I think I’ll add more Add-ons next time :P):
