Try to delete the pluginreg.dat file in the Firefox profile folder and maybe also delete addons.sqlite to reset the plugin registry database.

See "Re-initializing the plugins database":

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
