Hi today i upgraded firefox to the latest version 3.6b3 and i think it is the most stupid decision, most of teh addons are not working need help in downgrading it to stabler versions. i didnt find firefox 3.0 anywhere.
It's still in beta version so there will be some compatibility problems with some add-on. You can download older version of Firefox here : http://www.oldapps.com/firefox.php - Dynashox -
