I had firefox with my mac for last two years, all the sudden today I was asked to update so I did so, now it is not working
please help! I have always used firefox and it asked me to update today and now it no longer opens. It says "apple does not recognize developer" I have lost all my bookmarks because I deleted and tried downloading again. Still didn't work. MY info and bookmarks are gone and now I can even use firefox. I'm so disappointed. Please help.

Hello,
Your profile information is stored in a different location so your bookmarks and settings should still be intact.
Please see the article Firefox can't be opened after you install it on a Mac - How to fix.
