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. It does not allow me turn off autoplay. It blocks parts of page that I don't want it to block. Uninstalling. And I have Block Audio and Video selected in the Firefox Autoplay setting but no help there either. Frustrating.

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

Thanks for making the internet a safer place. Essential!

Saviour of the Internet

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.

Its not called browsing if you are not using ublock origin
