100% worth it and works seemlessly

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.

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 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!)

perfect

"Excellent and very customizable. Works on most websites with video, making it universal (unlike extensions for specific sites only, e.g., YouTube). Can configure keyboard shortcuts as well as speed jump increments."


"One of the best add-ons out there! Controls speed of every motion picture, even GIF! You can set your own shortcuts, so I set the same as YouTube. Now I can easily speed up to 6x or even more on YouTube!"

For those getting black screen with Amazon Prime Video - set the speed to what you want and disable the controller overlay and it'll work right away. You can use the shortcuts instead as well. In settings, you can permanently disable controller overlay by default.

This thing is reliable and easy to use, and it even is able to remember its settings when I sign into Firefox on another device so I don't even have to set it up again! Amazing

I can't live without this, literally the best and most used thing in my whole browser. I LOVE IT SO MUCH. 🔥🔥🔥
