Tried a few different extensions for setting video speed on the current page and this is the only one that does everything I want. Click on the toolbar icon, click on the speed you want, done.

As a bonus, you can completely customize the menu and add a button for any particular speed you want. Really convenient.

Please add another 'Big Rewind / Big Fast forward' buttons for 60 seconds steps.

Easily usable and configurable. Works on all sites, not only YT.

Perfeito, funcionou em todos os sites que eu tentei usar.

Лучшее дополнение из всех, которые пробовал. Максимально гибкое в настройках + может ускорять даже в тех плеерах, в которых не ускоряли другие дополнения.

I wish that we can set the default playback speed one day 🙏

I love how configurable this addon is. Also, the user interface is easy to understand, and fits right in with the look and feel of Firefox. Thanks!

hotkeys are not working when video are on full screen (increase and decrease speed). If you can implement it, it would be super helpful!

Works on WhatsApp for Audio and Video. Excellent. I wonder how to choose a default speed. e.g.: all videos and audio automatically play in speed 2.0

This add-on has saved me hundreds of hours.

extremely well though addon. I love the little icon constantly showing the actual speed. This is attention to details. Thank you. I cant find a Paypal to donate

Dont bother with any other speed control extension. This is the only one that works on browsers with various video source content. Great job guys.

SOOOO USEFUL!

Does it's Job perfectly
