Not work for some sites idk why, MV3 version is working better

When Caps-Lock button is active than add-on not working so I installed old version. Normally it works just fine.

This extension is the update of the video speed controller and is really good.

Please come with android support

It does its job but when you click on a video, the extension takes a while to work or doesn't even work until you click on it in the extensions bar.

I thank the Dev for the time they took to do this, which is clearly done with dedication and love.
But it does not work well.
I don't know why, but many many times it does nothing in Prime Video (browser, not app).
The original and the first refork still do wonder.
This one does too, when it works...

This is awesome!
Enables fine-grained change of the playback speed in all audio or video elements.
Improves the original plugin and does not break the onratechange event so it may be used by other scripts.

Great job done by M.A, it works perfectly in my FF while offering more advanced functions than the popular one. Just wanna say thank you!
