I assume you do not use NoScript, which allows you to manage JavaScript permissions on a site-by-site basis. (If you do, check whether you have blocked Google.)

Could you try Firefox's Safe Mode, a diagnostic feature for identifying setting and add-on problems?

I recommend first backing up your profile folder, which contains your bookmarks and other settings. See the section of this article on backing up your entire profile: Backing up your information.

Next, try starting Firefox in Firefox Safe Mode. Be careful not to "reset" anything permanently if you didn't back up.

Does JavaScript work correctly in Safe Mode? If so, you might disable all non-essential add-ons and re-enable them as needed. If not, hmmm, what could it be?

Thank You! Cannot believe that I missed the YesScript (NoScript) addon, Must have added it to Firefox 4 after the install and forgotten it in the uninstall/reinstall mess. Spent a lot of time on that problem and would have spent a lot more without your help. Thanks Again!
