This does nothing to prevent ads from running BEFORE the video starts.

works well and i trust it more than others. like that they dont sell out by allowing certain companies/replacing ads with other ads etc. I am not a developer so I am taking them for their word, do your own research if you want to confirm they are good but they satisfy my requirements :)

only had a couple days and very happy with it , if it shows any problems im not worry about it because Mozilla will be on it and it would just get even better

This addon is only for computer but not for phones but it is really good I personally try it it is work very well .

Great add-on for Firefox. works seamlessly and is easy to disable for certain websites when desired.

well done Firefox and thank you

Muito bom

Great stopping ads in pages I visit. Specially the ones that interrupt the page you are trying to read.

ONE OF THE BEST ADBLOCKERS AVAILABLE RIGHT NOW. TRY IT. YOU WON'T REGRET IT.
