User reviews

It would have been nicer if the extension allowed making exceptions for some sites via a whitelist.

PSA: This is no longer required if you're on version 88 or newer on any platform that uses Chromium (e.g. Chrome, New Edge, Brave, etc.). https://www.chromestatus.com/feature/6140064063029248

This feature is now baked into Chrome so the extension can be removed for most purposes. Where a site links to a target other than "_blank", e.g. "_potato" the same security issue still exists. Not sure if this extension only works with _blank links
