By far the best add-on out there to block adds.

This add-on is the sole reason I decided to switch from Chrome to Firefox initially. Sure, it is available in other browsers but it doesn't work the same.

Absolute must-have. I would also recommend installing Betterfox or similar user.js thing (like Arkenfox) for increasing privacy and security even more.

Fantastic app, this is the second extension I install on a new pc, the first been my password manager. I couldn't use the internet without it.

Awesome! AND I have been recommending Ublock Origin to others!

THE BEST! ЛУЧШИЙ!

No uBlock Origin, no surfing the internet.

A very powerful content blocker that stands out over many choices.

It's working as intended, with the ability to bypass many of those annoying anti-blocker scripts in a wide range of websites both in desktop and mobile.
Users can also add a whilelist and modify the rules to block or allow specific content.

The interface is pretty simple so even if you're not an advanced user you can work it out following a guide.

I has been relying on this add-on for nearly a decade and has never disappointed me. It have my trust.

Very good. Blocks ads as desired. Also, it improves web safety, I guess. But mostly I just watch youtube with this on to shame google.
