Firefox opens normall, but all functions (typing url, opening bookmark list, accesssing pulldown menus) don't work.

more options

Running Windows 7 and Firefox 15 on my desktop, Firefox apparently opens normally, but almost all functions are disabled (the pulldown menus - file, bookmarks- help, etc.) don't drop, I can't type a url, none of the home-page links work). I've screened for viruses and malware and none were found. I have made no recent changes in plug-ins.

I copied Firefox 15 onto a thumb drive using my laptop and then downloaded it onto my desktop, and my desktop Firefox remains frozen. I don't want to loose my bookmarks and cookies by deleting Firefox completely and reinstalling. What else can I do to restore the functionality??

Well you are actually running Firefox 12, I'd first update to Firefox 15.0.1. Update Firefox to the latest release

Then, after that, reset Firefox, Refresh Firefox - reset add-ons and settings. It won't delete your data, but will probably help the problem.

I updated to Firefox 16, and it works perfectly - I didn't need to use the Reset Firefox tool.

Amazing!

Thanks for your quick help.
