O melhor bloqueia todos mesmo, muito poderoso parabens aos dev's.

This blocks annoying contents quite sucessfully, the most amazing is the YouTube ad blocking.

The internet is borderline unusable without this or a similar extension, but uBlock Origin is easily the best of its kind.

very good congratulations al developer

Does the job for absolutely all the websites, I am very happy of it. Good job Raymond Hill!

it creates problems with pages loading, makes pages sluggish and unpresponsive, when using this extension / add on, my firefox pages were loading slower than without it. perhaps im doing something ' wrong' - but i dont think so.....

Can't even block Google ads. Have to have a GitHub account to let them know their product sucks. Don't have a choice to use an ad-blocker that actually works.

This add on works great! It works like it's supposed to and gets rid of all the unnecessary advertising, with the feature of letting me turn it off, when I feel I would like to support someone by watching ads or not. Great add on for all of us who browse and search online. This is how it should be!
