This is a great adblocker that Firefox managed to break somehow despite having it listed as a featured add on. It seems none of the adblocking add ons work for now so keep your fingers crossed this one comes back.

excelente solução para block anúncios indesejados

very effective and thorough

This add-on was great, until Firefox updated itself and gave me an error that this add-on (uBlock Origin) is no longer supported. Switching back to the older version (66.02) of Firefox did not help. Not the developer's fault, but it is definitely Mozilla's fault

Très bien
