Some of sites can't play video

I enjoy using this add-on on sites like YouTube but this add-on cause problems in playing videos on websites like Udemy and Amazon Music. Turning off this add-on on Udemy or Amazon Music solves the video or audio playback issue on those websites. I hope the developers look into this problem and make this awesome add-on even better.

Funciona bien, lastimosamente esta extencion afecta al reproductor de youtube debido a que no deja que se aumente la velocidad de reproduccion del video

THX - works fine for me ..

Bugs

Too bad it doesn't have a pitch slider- It also seems to interfere with YouTube's playback speed feature; the VidStreaming server gives no audio, only video. (while watching anime) (the others servers do, though?)

Great add-on. It really enhances the music on Firefox. But when it is enabled, the Youtube's playback speed is not working. I hope the developer will fix this issue soon.

Does nothing.
