IMPORTANT EDIT!!!! On YouTube a problem occurred. When I open a video, it turns OFF ABP. The instrument panel icon fades to grey and both sliders (This Website and This Webpage) turn to OFF position. Started July 30 2025.

I previously wrote a rather critical review of this addon. But after the recent "addons off" Mozilla disaster ("thank you" for supporting older versions users, Mozilla!), I realized that I was just an ungrateful prat! I didn't even realize just how much work this addon does in the background. I lived without it for three days, and I now fully appreciate it. It removes nagging ads from youtube, it remove audio ads from VK, it removes EVERYTHING!!! It does an AMAZING job. Thank you very much to everyone who worked on this addon!!! You are truly appreciated!!!!

Stopped working after the firefox update , shifting to Chrome now , good bye firefox

Как вернуть к работе расширения — открываете страницу about:config, находите там параметр xpinstall.signatures.required и меняете на false. После этого все установилось.
