How Do I Uninstall Safari Extensions On A Mac?
Safari Extensions can slow down your browser or cause any number of issues when installed from problematic sources. Removing browser extensions from Safari may speed up your browsing and generally help your Mac feel more responsive.
To uninstall or remove Safari Extensions: open the Safari app, go to Safari > Preferences (or press Command-Comma), then select the Extensions tab. You can then switch off all extensions or click "Uninstall" next to individual extensions to disable them on a case-by-case basis.
