it simply stopped working this past month.
I moved to ReelSleek wich is working flawlessly and is actually a better addon overall

works and no cpu problem (most of 1-star comments). thanks.

Stopped working a week ago.

This stopped working a while ago and it has not been updated since

Yeah it doesn't work and needs updating because instagram now prevents the slider from moving naturally.

doesn't work

Was working very well, like the other people said: Meta might have changed something. Video controls doesnt work anymore ... Hoping for an update.

Meta changed something. All extensions across all browser engines have stopped working for video control.

It doesn't work.

Firefox/Tampermonkey

the fullscreen fits based on the sides not the top and bottom so the vertical videos appear zoomed in

Definitely a necessary thing, though currently not working due to IG UI change. Might work again soon if updated.

use to work well until recently instagram updated their UI, developers plz fix this

Works great. Even included playback speed selection I was not expecting.
