The reason for the 3 stars: I've been using uBlock for about 2 years now. Extremely efficient against ads. But too demanding performance-wise.

Basically sometimes my FF becomes literally unusable, it freezes up for 5-10mins. I sometimes have to restart it 3-4 times to get it to load my first page! At first I thought it was FF itself and was actually looking for an alternative browser, but then I got a hint that it could be the ads + uBlock. So I disabled it and IMMEDIATELY FF started normally as if the freezing that was happening before did never happen. I was really shocked that uBlock can have such a negative effect performance-wise. But now I am sure it is uBlock.

I am going to switch to another probably less efficient adblocker. But I cannot sacrifice that much performance even if it is for good ad blocking.

Якби я міг встановити лише одне розширення, безсумнівно, це був би uBlock Origin

You guys rock!

those who don't use this extension are stupid or donkey

Was hesistant to switch from ABP that I have used for years, but uBO was pleasantly easy to set up. Very much "fire and forget", it quietly does its job in the background, and has a wide range of features and capabilities. Possibly my favorite add-on overall.

Effectively thwarts a multi-billion dollar industry

Seriously so good. Works across all my browsers and operating systems out of the box. Especially amazing on the mac, where working with Safari can be a gnarly experience.

I'm trying to figure out how to give you guys money for making this extension software but can't -- is there a link on your homepage I'm missing?

Thanks!
