How do you disable extensions in Safari?

To turn off or uninstall extensions:

Choose Action menu > Preferences and click Extensions. (The Action menu is near the upper-right corner of the Safari window, and looks like a gear.)

Click the On/Off switch to turn all extensions off.

Click the Uninstall button for an extension you want to remove.

Any changes you make to extensions, including installing and uninstalling extensions, take affect when you navigate to a new webpage or refresh the current page.
