Custom default play speed and even custom speed increments, works with the existing youtube keyboard shortcuts.

Works pretty dang seamlessly! Love the ability to add your own custom values, but keyboard shortcuts (rather than single-increment arrows + a clumsy drop-down list, which gets cut off at the top if you have lots of individual speed values) would make this even more intuitive. What's really missing is pitch control—all the other add-ons that manipulate pitch have clunky UI or fussy functionality. Regardless, this here's the best speed control add-on I've yet to come across.

I appreciate this extension, but please add the ability to create keyboard shortcuts for adjusting speed! I would really like the ability to use "+" and "-" to adjust instead of being stuck using the default controls.

EDIT 8/11/2025: Speed control on the video player is no longer aligned with the new YouTube player design.

Firefox. Youtube Custom Speed. Instructions are very poor. I cannot get YT to change any speeds at all. A good app with a poor instruction set, is a poor package.

elegant and useful! special respect for the ability to create custom speeds!!!

some talk too slow in their videos, this quickly helps

Simple, elegant, and does the job.
A few improvements I can think of:
Let us use the mouse wheel on the icon of the addon to increase/decrease speed.
Let us customize the keyboard shortcuts, or disable them completely.
These aren't must-haves, but would be nice.
Still, 5-star, and thank you.

Works seamlessly on my M1 Air. Very minimal. Non intrusive. Customizable. The developer is very responsive. Let's get this guy a beer

There is a problem for those whose keyboards are not originally English and this causes that when you do PRESS SHIFT AND " . " OR SHIFT AND " , " then it reverses the speed and when you press CAPS LOCK TO MAKE IT BE IN English LETTERS then it does not allow you to use the keys at all and they do nothing. PLZ FIX IT PLZ
