Safari 6 (OS X Mountain Lion): If you need to remove a plug-in

If you need to remove a plug-in

If you have recently installed a plug-in and notice that Safari runs more slowly, quits unexpectedly, won’t download files, or exhibits other performance problems, the new plug-in may be the problem.

  1. Quit Safari.
  2. Locate the plug-in. Plug-ins are usually installed in one of these folders:

    • /Library/Internet Plug-Ins/

      To open this folder, go to the Finder, choose Go > Computer, open the startup disk, and then open the Library folder.

    • ~/Library/Internet Plug-Ins/

      This folder is in your home folder (represented by the tilde ~). To open it, go to the Finder and press Option while choosing Go > Library.

  3. Remove the plug-in you recently added.

    You may need to enter the account name and password for an administrator account on your computer.

    Important: Removing a plug-in might prevent Safari from doing certain tasks, such as playing movies.
  4. Reopen Safari.

    If the problem is fixed, contact the developer of the plug-in to report the problem and to see if there is a newer version of the plug-in.

Removing plug-ins may affect other apps on your computer that use plug-ins.
