# 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 find this folder, open the hard disk icon, and then open the Library folder.)

- ~/Library/Internet Plug-Ins/

  (This folder is in your home folder (represented by the tilde ~). To find it, open the hard disk icon, open your home folder, and then open the Library folder.)

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 If the problem is fixed, contact the developer of the plug-in to report the problem and to see if there is a newer version of the plug-in.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 applications on your computer that use plug-ins.
