Yes it blocks ads but YouTube knows you are using it and forces a delay as long or longer than the ad it blocks

10/10, 5 stars, bet extension to date. Blocks all ads, no more of those annoying ads that take you into a new tab. No ads on YouTube, no ads at all. And you don't even notice it's there. Recommend to anyone, this is hands down the best ad blocker avaliable.

A very powerful content blocker which has helped me in the past when I've unknowingly clicked on dodgy links. Most importantly for many, it works on YouTube.

El mejor hasta ahora por mientras no funcione por completo el del mismo navegador

Best ad blocker extension by far, the zapper feature is a huge plus too.

Amazing, just amazing. I can finally watch YouTube in peace without being interrupted by 3 consecutive ads basically every 5 minutes. Doesn't require a heavy cpu load from your computer and runs smoothly. UBlock Origin takes you back to a time when the internet was what it was supposed to be, majority ad-free. Props to the guy who made this, you are a legend.
