This extension is a must have when watching YouTube. I have never seen a single ad since I started using it in March 2026. It blocks all YouTube ads and allows you to immediately start watching videos, unlike another adblocker I tried called Adguard, which would make the screen freeze whenever there's an ad, then you need to reload and wait for a few seconds to watch the video. By contrast, uBlock Origin is a much smoother experience.

By the way, uBlock Origin blocks almost all ads and redirects from every website I visited. Besides, I can customise the filter list to block specific components of a website that i don't want to see.

Thank you for being a hero, keep manifest v2 and uBO alive on fox!

Just what I you need to block anything you don't need, save bandwitdh, block ads, etc. Ublock has made using firefox problem-free.

You'll never see an ad again. Works like a dream, no wonder Google hates it.

ublock origin for a calmer internet

Absolute the best and a must-have extension.

TOP STAR RATING PLUS! Sable, dependable, reliable,and rarely any issues; but if a block occurs you can always stop block, set as an "always" exception site, or exception always page.
