^^ Never experienced such problems yet.. try reinstalling it 
clean it out completely… try uninstall, then delete firefox folders, also deleted the profile in your user directory in your OS, get rid of all extensions and re-download latest versions… then reinstall FF3…
Nope, its the most stable firefox i must’ve used. Period. Apart from the compatibility problems of the old plugins installed which should be fixed sooner or later
mine doesnt open up the tabs from last session…
