The best. Not detected by websites that it is installed. Thank you.

Best ad blocker extension right now. Takes very less resources and yet filters most of the intrusive ads from the website.

One day I didn't use uBlock and I could barely read the internet. Now, with uBlock, I can read all the clickbait without giving people money. Have you seen YouTube without uBlock? It's so bad an ice pick lobotomy would be preferable. Now I have to actively seek out stupid ads people on Reddit are talking about. Good job! Thanks!

Not only is it doing its job it is easy to install and I love the reduced amount of ads showing up on my screen at critical times...

The best ad-blocker for Firefox at the time of writing imo. I used to be a long time user of ABP, and only switched over to uBlock Origin around a year ago. uBlock Origin is indeed the most performance-friendy blocker, yet it also appears to be the most effective and customisable. Plenty of options for those who want to fine-tune, yet also perfectly fine to use without any config which makes it great for corporate deployment and power users.

Lightweight, works great

The best ad-blocker out there. It's more that an ad-blocker though.

Very useful
