Update: It now works exactly how I hoped, and I can change the speed of videos and it works. Changed my rating from 4/5 to 5/5

Amazing add-on. I use it all of the time. Recently it won't let me speed up YouTube videos while I have this add-on enabled which kinda sucks. Before it would just not let me speed it up if this add-on was in use, but now I have to fully disable it from Firefox to speed up the videos.

This plugin completely destroys slowmo playbacks for me (for example: 0.5 or 0.75 speed on Youtube).

Recent Update seems to have broken the ability to watch a lot of videos.

Works great except for the past week, it's caused twitch clips to not load.

Edit: Addon is fixed and works great.

This app really works unlike a lot of other app simple to use unlike other apps.

Worked great until the update about a week ago, now I can't watch twitch clips with it enabled so I have to keep turning it on and off

works well. but it doesnt let you play videos on different playback speed (even you are not using the extension). Uninstalled.

After the latest update,
youtube payback speed not working.
(I checked by enable-disable this extension)

This extension doesn't work well for changing the audio level of a google meet as it seems to only amplify one audio source which isn't useful if you are meeting with a bunch of people. it will get the job done for youtube and other things like that. For whatever reason it also broke video playback on udemy.com by existing.

I just wish it saved the setting for each page; besides that, it's perfect.

This addon is currently bricking Firefox's ability to play Twitch Clips. I keep getting Twitch Error #4000. This started about 3-4 days ago. It was working fine before this.

Very good add-on, does what it says it does. great extension

Last update broke all videos.

Edit: Issue seems to be fixed, thank you!

This has broken clips on Twitch.tv for some reason. I will change my rating if this is fixed!

It's breaking Twitch clips and some html5 based video player sites.
As soon as I disabled this addon, every video worked just fine.

Unfortunately it disables the option to change video speed which makes it unusable for me.

If it's fixed I'll change it to 5 stars.

There should a global option other than that its good
