I use the Video Speed Up many times. I heavily rely on this tool. Thanks!!!

Very good and also works on mobile

Doesn't work.

this is very great extension for firefox, I found here that I wanted. I will recommend everyone to use this extension.

It works.

Works but has very basic features, the increase is only by 0.25 steps, and the websites don't remember the change.
The classic Video Speed Controller and its two reforks do much better.

Imagine my surprise that video speed up was also by the same dev that made Loudness! wow...
I use this extension almost every day to help me thru the many videos. Yes, there is a speed adjuster in Youtube, but it only goes to 2.0.
I find this to be easier and better (as well as more convenient) Thank you for making this!

VERY Good

Works good but needs better design like + and - buttons. Please make it

it works,but GUI isn't perfect.

Really good.I suggest to add hotkeys which will make it easy use.Thank you for your work.

did NOT work

Please, move the controls into the YouTube speed control buttons. i mean, i do not like any icons distracting me in the browser. Just add x3 to the standard sets in the YouTube player. Example here: https://www.wikihow.com/images/thumb/6/69/Speed-Up-YouTube-Videos-Step-9-Version-2.jpg/aid6356714-v4-728px-Speed-Up-YouTube-Videos-Step-9-Version-2.jpg


OR HERE (there are x1.5 and x2, but there is no x3). Please, add x3 here for more comfortable experience: https://pocketnow.com/wp-content/uploads/2019/08/5.jpg

Anyway, the functionality you gave is a good present, thanks. But, in the screenshots which I showed you, the buttons are in a better place - in the YouTube window, and NOT somewhere in some button and some other button and next button.
