Updating or re-installing your plugins
Many problems with plugins can be solved by updating to the latest version of the plugin.
If updating to the newest version of the plugin or reinstalling it does not fix the problem, you can leave it disabled.
Manually uninstalling a plugin
If you can't use an uninstaller program to remove a plugin, you can remove it manually:
- Skriv about:config i adressefeltet, og tryk på tasten EnterRetur.
En advarselsside vises måske. Klik på knappen for at gå til siden about:config. - Search for the preference: plugin.expose_full_path.
- Double-click on the plugin.expose_full_path preference in the list to change the value to true.
- Enter about:plugins into the Location bar and press EnterReturn to display the About Plugins page.
- Each entry in the About Plugins page will have "File name:" followed by a path. Use Windows Explorer to navigateNavigate to the folder shown for the plugin you want to remove.
- Rename the file to add an X in front of the filename (for instance, npswf32 becomes Xnpswf32).
- Double-click on the plugin.expose_full_path preference in the list on the about:config page to change the value back to false to avoid exposing the plugin path to websites.
The plugin will be removed.
