I initially thought that I can only set the speed for all the tabs. After reading the description, and digging around a bit, now I have realized that I can set the speed only for one tab(as I only need it for spotify) which is really good, this extension is exactly what I needed

very nice. it's light and remembers speed globally (unlike others, which don't or are not updated)

挺好的

One of the most useful Firefox Extensions

It works like a charm. and the extra things like pinned tabs with different speed is a bonus

nice

I installed this specifically for Spotify playback. For some reason, Spotify doesn't support speed control, even for podcasts, on their website. Once you install this addon, you will have to "reload" the Spotify site, then it works! The controls are simple and easy to use, and you can adjust the speed while something is playing. Haven't tried it with other sites yet, but the other site I use the most (YouTube) already supports playback speed control.

Me gustaria que al pasar de x4 el audio no se perdiera.
No tenia ni idea, gracias
