I DON'T LIKE IT

This used to be good for YouTube ads, but now it basically doesn't work. Ads (especially long ads) still play and it will refresh trying to play an ad sometimes dozens of times before finally playing the video. This add-on needs to be fixed or removed.

doesnt cut out ads

Wenn ich das Add-On vom Internet laden möchte, kommt die Fehlermeldung :
Dieses Add-on erfordert eine neuere Version von Firefox (mindestens 52.0). Sie nutzen Firefox 47.0.
Inzwischen bin ich aber bereits bei Firefox 61.0 (MacOS 10.13)

not goood

Multiple memory leaks, makes youtube around 2.5x slower on slow pc's, and constantly does NOT do what its told. A terrible, flawed extension. Do not use this until he/she decides to make this extension feasible in any way.
