Nice bro. My Add-on "Streaming enhanced" also has Speed Control for Netflix. I also programmed and released my addon because the others were worse. Keep up the good work.

Works exactly like it is supposed to. And it works on other websites too!

Please add 1.25x and keyboard shortcut. (Maybe just like Youtube's shortcut shift . and shift ,) Thanks for the addon.

I'm learning a new language and your plugin is exactly what I was looking for <3 just like the user before me said, if it had a customizeable keyboard shortcut to increase / decrease speed on the fly, it would rock even more! cheers

yes work well, and actually is a good idea, even for people need to learn language they listen slow, or go fowards ,, will be amazing a sort of controll like + and - or mouse to control the speed, congratulations!

Could you add a 1.25x, 1.75x, 2.25x, and 2.75x? Thank you.

Otherwise it works great!

A TERRIBLE THING! But, a terrible thing that works perfectly. :)
