Breaks Youtube videos

Doesnt work on youtube

Doesn't work. Waste of time, why is this still even here?

i thought since the end of adobe flash i would use this instead but it just breaks firefox and autoplays all videos EXCEPT youtube... instead it BREAKS YOUTUBE! will not use anymore and will find another way to play videos without flash

Ich konnte keine Youtube Videos mehr abspielen, aber als ich den Player wieder etfernt habe ging es wieder.
