Works very well. For me it has always blocked ads 100%. Yes, even on youtube flawlessly still to this day.

THANKS !!!

The most essential browser extension that is a must have with every new install of a browser.

Great and would be 5 stars if my choices were backed up to the cloud. If you reinstall FF you lose everything and have to start again.

its work!!!!

Possibly the best and a must use addon out there. Not just because of ad block ability but there are so many useful functions in it.

Not even Youtube detects it, 10/10. And fuck Chrome!

i made a mozilla account just to give ublock origin 5 stars its awesome. download it now. works on every site <3333

Great ad blocker I have never used a ad blocker better then this
