I recently updated to the recent Firefox version 40.0.2. Now for some reason, all of my installed applciations, backgrounds etc, has been removed and put into a seperate file called (Old firefox data) i am completely unable to re-install any of my old applications, it simply says a problem occured, no matter what i try to download. I can also no longer access quite a lot of my bookmarked pages, alla i recive is a "Felkod: sec_error_bad_signature" (Swedish) And yet an even stranger problem is haunting me, i cant access the 'Mozilla.org/se/com/etc' pages any longer, it looks the whole page is still in development, i went into Windows Explorer (See how desperate i am!??) and went to Mozilla.org again and suddenly it works again, but not i Firefox. I have no idéa what the problem or problems here is, but please help me, i cant use a browser that isnt working properly and i DONT wanna switch to any other browser unless i really, really, Really need to. Yours, Adam Maxe
