Every single extension I have is broken. Uninstalling and re-installing doesn't work either. They say they'll be updated when Firefox is restarted, but I can't even open the preferences for each plug-in.
Not a solitary extension is working. Many of them say that they'll be updated when Firefox is restarted; some of them ostensibly appear to be working, but clicking on the 'preferences' button provokes no response. I have Firefox 3.6.13. I've tried uninstalling and then re-installing one of the extensions (Stumbleupon) but to no avail. Do I need to be re-installing Firefox here?

This can happen if one of the files that stores details on installed extensions is corrupt. To fix that see the section on corrupt extension files in the Unable to install add-ons (extensions or themes) article.

Worked a charm. For reference, I think it might have been Firebug 1.6.0 that killed everything,
