This extension is the only reason I moved to Firefox. I used it for years on Google based browsers, but this month it stopped working there. Here I am.

Excellent!
It works very well.
It blocks trackers and ads very well.

The best blocking add-on here. Love it

Extension does not stop autoplay of videos on espn.com. And I have Block Audio and Video selected in the Firefox Autoplay setting.

sem essa extensão eu teria desistido da internet, muito obrigado!!

Thanks for making the internet a safer place. Essential!

Saviour of the Internet

Can't live on the internet without this.

The BEST tracker/ad blocker : completely open-source, managed by volunteers, and very light on RAM/CPU resources!

It's completely broken. After 30 seconds no data from any website can be loaded and my CPU goes into into overdrive. The second I disable Ublock the temp drops rapidly and everything starts loading again. Tested multiple times. Was great while it lasted but it is unusable in it's current state.
