It's the best ad blocker ever. Safe, efficient, and interesting. Unlike Adblock Plus, which had vulnerabilities back in the day, uBlock Origin is more than just an ad-blocking extension. It's a must-download if ads distract you while you work. I'd give it 100 out of 100 if I could.

The magnum opus of ad/tracker/annoyance blocks. Also very easy to make your own filters to disable or modify web elements - use the "element picker", not the "element zapper".

The best adblocker right now. Blocks basically every ad

i owe u my life fr

uBlock recently started preventing me from accessing the comment pages on stories in the TorontoSun.com website, even though it's blocking ads throughout the website. If I disable uBlock, ads are everywhere but I can access the comment pages. Very frustrating!

Best extension ever. Best ad blocking tool. Perfect

Mozilla should just integrate ublock origin into firefox instead of the useless "enhanced tracking protection" since browsing the modern web without a proper ad blocker is impossible these days

Amazing, I wasn't able to use a site because the ads made the performance on my device horrible, but this fixed that!

Classic addon that makes the internet readable and also defends privacy.

Works ok but does not work as well or as comprehensively as Ublock did on chrome. Frustrating because I went from seeing NO ads to having to block the same ads again and again once a page is refreshed.

Supposedly ublock works best on firefox, so if anyone knows how to help it take full effect, please comment on this. Because I am so frustrated trying to get rid of ads on firefox with this!!

Great 😃
