I'm posting back on this thread just to let you know that I successfully compiled firefox including the italian dictionary (which is an addon), but when starting ffox for the first time the addons popup showed up and told me that the dictionary version wasn't compatible with that version of ffox... the strange thing is that I was using that same dictionary on that same version of firefox with my default user and everything worked like a charm... however, I uninstalled the addon and reinstalled from the addons popup and it worked...
I'll keep investigating in this sense...
PS (a bit offtopic)
I've successfully built a version of firefox using qt instead of gtk2 on slackware64-current... it isn't usable at all but it's funny to see it... I hope the guys at cairo keep working on cairo-qt...
bye
