Hi, there are no ad blockers as such, but there is Enhanced Tracking Protection: [[Enhanced Tracking Protection in Firefox for desktop]]. You can disable it per site, by clicking the shield icon at the left-hand end of the address bar whilst on a site; or to turn it off, open the 3-bar menu > Options > Privacy and Security (Browser Privacy), then set Enhanced Tracking Protection to Custom and deselect all the boxes. ''If your question is resolved by this or another answer, please help other users by marking the best reply as Solved. Thank you!''
