Very good. Blocks ads very well.

uBlock has been one of the best additions to Firefox since, maybe, NoScript. It's capabilities and features should be built-in and standard. The web is a troubled place with ads, tracking, and malicious connections in nearly every request.

Absolute life savers and a must need for browsing the web these days

I love you guys so much. It's not so much that advertisements are terrible, it's that the nature of the internet is so terrible. I like being able to drive my old macbook or thinkpad and not have to worry about 4 dynamic ad hogging up my system resources just so I can read a recipe. I know that this isn't just an adblocker, but it's a content management suite. Being able to choose what I want to see is my right, and I appreciate all of the efforts that the uBlock team puts in so that I can exercise that right.
