Hello alihafeez337,

Maybe you could give this add-on a try :

https://addons.mozilla.org/en-US/firefox/addon/videospeed/

See : https://www.ghacks.net/2018/04/15/video-speed-controller-for-firefox/

And then there is this add-on :

https://addons.mozilla.org/en-US/firefox/addon/playback-speed/

But, this is not a valid solution. Is there is a fault in the browser, it must be solved.

I don't have that problem (see screenshot), so I'm afraid that it's something on your end.

Maybe an add-on that's causing this (if you have any add-ons, that is) ?

Hi alihafeez337, could you clarify what is happening when you are using YouTube in Firefox: is the "gear" button available or missing, if it's available, does it have Playbook Speed as an option or not? Where is the process breaking down?

Everything works fine now, there was this extension "Audio Equalizer" (https://mybrowseraddon.com/audio-equalizer.html) creating the problem. Thank you very much.

I'm glad you found the culprit - well done !
