I've seen this feature in the YT-Vanced app for Android and wondered if there is somthing like that for Firefox too. Well, here we go! Works like a charm!

Une extension vraiment pratique pour passer ces sponsors(Raid, NordVPN...). Moi même j'ai sauvé au total 6h16 pour 286 personnes!

Muy buen complemento. Lo recomiendo, ya que puede ser muy molesto ver sponsors y demas. Sin dudas, creo que este addon sumado al Ublock origin hacen de gran ayuda.

Highly recommend installing this if you want classic non-advertising in YouTube videos. Ability to configure what you do not want to see. Problems with this still are user submissions and ease of override content itself.

YES

The best add on since the original ad blockers was invented. Works amazingly. I don't know how I survived without it.

I installed this addon today, and right from the get-go, this addon seems to save a LOT of time! Thank you!

sponsorblock may be the best ypoutube add blocker at the market
