Great extension but as of Firefox version 153, there has been an update by Firefox that no longer allows you to use your shortcut keys to change playback speed when viewing local video files that you drag into your browser. This isn't a frequent use but sometimes it's nice when you want to watch a local video and use Firefox's PIP feature for watching and browsing.

If anyone knows a fix, please feel free to let us know. Thank you in advance.

I love focused extensions with a clear purpose like this.

Because I'm slightly paranoid I did a quick check of the source of v0.6.3.3. The code is minimal and clean, without any wasteful bells and whistles, and doesn't do anything else than the thing it promised to do.

I should note that it has not been updated in 5 years at this point. I personally consider that a *good* thing because that suggests I don't have to worry about unexpected changes or functionality being taken away. It also means the extension predates vibecoded slop, which is a bonus. On the other hand, there are quite a few open issues on the github tracker, and if you run into one of them it's unlikely to be fixed, so YMMV.

But in my use-case (desktop browser) it works very well.

100% worth it and works seemlessly

need a patch for changing playback speed with mouse scroll

It's a fork that is not maintained anymore.

Let's me speed up a long YouTube video so I can watch it faster. Reload the page you want to use it with in case you don't see it.

This was amazing several years ago, but starting to break down because original author (codebicycle) no longer has time to maintain. I've switched to Speeder, which is a revival of this original.

Works flawlessly for me. I run Firefox on Ubuntu. It also worked well for me on Windows and Firefox before I switched to Linux.

I absolutely love this addon/extension for Chrome, but when added to Firefox, MANY features of Firefox have become unusable. Even things like ctr+f to find text, maybe options that are available when you right click a page on your mouse. PLEASE FIX!

I can't speak to how it works on other sites, but my teacher added additional videos to a Canvas post that had no ability to fast forward and this is saving me. It can be a bit janky but it's nothing I didn't expect from an extension adding a non-native feature. (Though, edit, the clunkiness went away once I used the keyboard shortcuts!)

Works, but really slows down loading on certain websites (like Reddit) making them annoying to use. Will be uninstalling.

perfect

Seems to work good most of the time; but on Youtube, sometimes it will be unresponsive, so I can't change the speed of the video. I have tried disabling all adblockers in case they were interfering, but they don't seem to be the problem. This has only occurred on Youtube so far.

its mediocore... after i got rid of it (i belive) that the speed of the videos got fucked permentally, plz help

Pleaaaaaaase fix compatibility with Paramount Plus. For some reason, only on that website, I cannot hide the UI. Pressing the hotkey will make it go away for a split second, and then immediately return.
