Works perfectly and even in players that dont support any speed changes by themsevles, which is a big plus
Only 4 stars because there is no option to make exceptions for some sites, where speed change is not needed or native speed change is sufficient, or at least a button in the interface to disable extension, opening extension manager every time is a bit repetative

Works great on every site I used it on. Even streaming sites that do not support speed changes. No additional features needed by me. No complaints. So, 5-stars.

I don't say that many things are good, I'm not used to praising programs, but this is one of the best, most useful add-ons! I use it with joy every day. Huge thanks to the creator! This add-on is so great!!!

This would be great, but one feature is missing - to add exceptions that the extension acts on.

Working Prime Video

Thank you, it works perfectly.

Doesn't appear to do anything with the playback speed. No idea what it's doing in the background - uninstalled.

Merci infiniment <3 ! thank you so much <3 !

It would be nice to have different speeds in different tabs / pages. And get the 4x key back.

Can you make a mobile app version of this?
This app has improved my life exponentially. This app needs to be mandatory on all versions of Firefox for me. I'd donate, but I'm in debt right now. This guy isn't even asking for money. I hope I remember to when I'm not in debt: https://geekyadvisor.blogspot.com/ I still wish for 2.75 and now 3.75 and 4.75, and even 1.75. They improved the app and fixed the audio issues. I use 3.5, 2.5, 1.5, and 1.25 all the time. This app is so great.

the october 3rd update removed the 3x and 4x buttons. not cool.

Why I would need an extension to change the speed to the same fixed values, the native page already allows to me? I need something between 0.75 and 1.
