Works great, does exactly what I wanted it to, except for one thing:

When the add-on is enabled, I can't play two videos at the same time (say, I have two YouTube tabs open for, say, a podcast with no background music and background music). I don't know why; I don't know if that's a bug or a feature, but if it's a feature, it's a bad one, and I'd at least like to see an option to disable that.

If it is a bug, please fix it. I'm adding it as an issue on your GitHub.

Keep up the good work, though. Again, I gave this a 4/5 for a reason.

Very usefull addon, but I'm having a issue. IDK why but this addon is making it impossible to load some sites. And it happens only at Firefox, e.g. for acess this site: https://www.noalvo.com/ I have to disable the addon, If I turn it on, the site dosen't load... I'm also thinking that the addon is responsable to use a lot of ram memory

Now I can't live without this

I do not like using keyboard. I like my mouse. Also, put the controls together with the YouTube's controls. I mean, add x3 to YouTube's standard set of buttons. i do not like any additional icons in my browser. Just mix your soft with YouTube's GUI in the browser window.

I absolutely love this add-on. It's one of my favorites. Unfortunately Firefox has an issue with the audio on sped up videos. It's not the fault of the add-on. I really hope it gets fixed soon. I've been using this extension for a long time on Chrome.
