Application Extensions

Extensions help you to customize apps or browsers on your Mac. However, having too many of them may cause your Mac to slow down. Furthermore, some extensions may have been installed automatically, so you don’t need them. With App Uninstaller you can get rid of all useless extensions in just a few clicks.

Delete Applications Extensions
