I am beginning to be asked by websites to turn-off ad-blocker. Just realized that Firefox has an ad-blocker embedded in its software. When I go to Add-ons & Extensions, Ad-Blocker is not listed so that I can turn it off. Suggestions on finding ad-blocker and having the ability to turn it off and on would be appreciated. Thanks

This can be about Enhanced Tracking Protection.

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection
