How to disable a plug-in in Mozilla FireFox, versions earlier than 3.0
FireFox (versions earlier than 3) allows you only to uninstall a plug-in, but it will be deleted from all browsers. As far as the plug-in is insecure, its use may be harmful for any browser, therefore you should delete it without any doubt you can reinstall it as soon as a patch is issued.
We recommend you to update your browser up to the securest version, and then choose which plug-ins to delete, use helpful features and be protected from the known threats. New version usually includes additional features and patches for detected errors.
