Removing or Disabling Extensions

Having too many browser or app extensions can slow down your Mac. Moreover, there may be some features that you don’t use or plugins installed automatically that you even don’t know about. App Cleaner & Uninstaller allows you to remove all these useless additions.

In the Extensions tab you will find the files of the following types:

  • User Extensions

    • Launch Agents
    • Login Items
    • Installations
    • Web Browser Extensions
    • Screen Savers
  • Core Extensions

    • Preference Panes
    • Internet Plugins
    • Widgets

Follow these steps to remove unneeded extensions on your Mac:

  1. Click the Extension panel (letter “E”) to view them or use the Cmd+2 shortcut.

In addition, any of the listed items can be added to the “Skip List” so that they will not be shown in the scanned list. Make a right click on the file and click “Add to Skip List” or go to the “Preferences → Skip List” tab and there add your items.
