Firefox Remove plug-in manually

If you can't use an uninstaller program to remove a plugin, you can remove it manually:

   1. In the Location bar, type about:config and press Enter.
   2. Search for the preference: plugin.expose_full_path.
   3. Double-click on the plugin.expose_full_path preference in the list to change the value to true.
   4. Enter about:plugins into the Location bar to display the About Plugins page.
   5. Each entry in this page will have "File name:" followed by a path.
Use Windows Explorer to navigate to the folder shown for the plug-in you want to remove.
   6. Rename file to something other than its normal name - e.g. npswf32 becomes Xnpswf32

The plug-in will be removed.
