Great preventing pop-ups.

YouTube videos randomly skip ahead like 10 seconds. I assume these skips are where adds would be. Very annoying having to go back and sometimes not being able to tell if there was a skip or not.

Simply essential, it is impossible for me to surf the internet without it.

Blocks far too many safe websites, and can be a serious pain in the butt sometimes. Perfectly good web pages are blocked for no apparent reason. Tends to block too much content. The good thing is I found some code online and it's the only app that actually blocks those obnoxious Google sign-in popup prompts, for which Google should be sued for harassment.

Works perfectly in the background, requires no input. When I use other peoples' browsers I am shocked by how many ads are on the internet. Thanksfor making the web look so clean and pretty

Works amazingly and is easy to use, but still very extensible! Hats off to the devs!

Without a doubt the best ad blocker I've ever used, and that's saying a lot. I've been an Internet user since 1994, and used Firefox since early beta, when I switched from Netscape Navigator. I'm not bragging, but merely explaining why this review can be trusted. Thank you, uBlock, Raymond Hill! As a fellow software engineer, I can honestly say your work is pure art: stable, reliable, efficient and with a small memory footprint! I love your other extensions, too.
