Tabs, history, bookmarks, basicly anything and everything that was crucial are gone, seemingly after recent update. I had similar problem a couple of month ago and didn't find clear solution back then, but it all got sorted out maybe in couple of days (probably with next update or something?). Well who would've thought i would get screwed like that a second time. So i can't tell for sure whats caused it or how it got fixed. What i manged to figure out both times this happend is that somehow i have 2 versions of Firefox Profiles judgin by the dates of the cursed updates. So i guess my stuff is still there but i can't acces it. Also worth mentioning is that both times i've got screwed by updates, my FF shortcuts from Quick Acces pannel stoped working and i needed to drag'n'drop em all over again. Im at totall loss here, i know the info i've provided is almost nonexistant but if anyone knows whats up i would be greatly apreciative if you could tell how do i fix this and prevent it from happening in the future.
