This is the best adblocker is have used.

Works great, its so much nicer surfing the web without ads taking up my valuable screen real estate. You just install it and it works. Occasionally a website may break, but you just disable it on that website and you're good to go! To finish things off, trust me YouTube is a much more pleasant platform to use without a bunch of questionably appropriate ads popping up constantly. Overall 5/5!

I switched to Firefox from Chrome solely for uBlock Origin. Thank you so much to the creator/developer(s)! Genuinely increased my quality of life.
