Bellissimo!

Very good add-on that is great for my use. I don't really want to block all ads, just abusive ones and ones that I think are just fake or irrelevant for the webpage/article that I am currently reading. Highly customizable to your needs and I wouldn't really surf the web without it.

DEUTSCHE Text-Version :
Hey Leute, was geht ...?...... Von allen hier von mir getesteten Ad-Blockern ist der "uBlock Origin" von 'Raymond Hill' für mich persönlich bei weitem DER BESTE, weshalb ich ihn auch schon seit Jahren nutze !

Er bietet auch viele interessante, individuelle Einstellungsmöglichkeiten und hat Antworten auf so manche Frage parat. MEINE SUCHE ENDETE also hier. - Bleibt nur noch zu sagen:

Vielen Dank an den Entwickler, Mr Raymond Hill ... und einen schönen Gruss von
Mr. TwoDeads (but) StillAlife, Fulda/Hessen/Bundes-Republik Deutschland/Europa/Planet Erde/'griiins'

Many thanks to the developer, Mr Raymond Hill ... and a nice greeting from Mr. TwoDeads StillAlife, Fulda/Hessen/Bund-Republic of Germany/Europe/Planet Earth/'smieeele '
