Firefox screwy after update HELP


New member
Hi friends,
A recent Firefox update destroyed all my bookmarks, all my passwords and all my plugins and settings (kinda like a blank install). I have the important bookmarks and passwords back (like Kitty-Kats) but a few strange things are still out there. I used to have something (script? plugin?) that gave me a bypasser and auto fullscreen for all single images for the various image hosts. Don't know what that was or where to look for it???
Another weird one is that Keep2Share no longer words for me: clicking Solve Captcha does nothing at all???

Any help appreciated!
