Cloudy

Doesn't work for me but if it works for you 10/10 extension

Hey, I love this extension it helps me to reduce my screen time on sites like discord, reddit, etc. however I was using it on YouTube music but I noticed the progress bar was weird, other than that it's a amazing extension for productivity

I tried 4-5 browser grayscale extensions; Cloudy wins so far! If the developer addresses the fullscreen video issue (w/ amazon, youtube, and virtually all other fullscreen video) then Cloudy will easily be the best.
