As far as I'm concerned, this is the single most important addon available for Firefox. My tip for new users is to go through the Wiki instruction manual on the developer's Github page, and learn about "hard" and "medium" blocking modes, as well as dynamic vs. static filtering. If you're anything but the most basic of computer users, a medium/hard blocking mode will help you get more out of uBlock Origin. It's really not hard to accomplish.

I just wanted to say thanks for the great work, I really appreciate the plugin!

great !

good！

Lighter, more efficient, more powerful than other blockers. Long live uBlock Origin!
