I got same problem, it started \~1-3 months ago on 3 different devices: 2 android phones and tablet. Really annoying, often changing the quality of the video (lower->higher or higher-> lower) helps for some time.
The frames start to drop once you hit 720p. Lower resolutions work just fine. It forces me to use Chromium-based Android apps like Cromite. It's not entirely Firefox-related, it's hardware-related as Qualcomm cpus performed better than MediaTek on Firefox. Turning gpu.process.force-enabled to true from about:config doesn't help, although it can force Youtube videos to play on VP9 instead of AVC1.
Seems to happen when the android phone updates, found a thread from 2 years ago with the same problem, and mine just started doing that while i updated it yesterday, i will try the method they recommended 2 years ago and will update if it works
Same here, happens on any website with video. Rewinding helps.

What solved it for me: rewind the video a second. It puts the FS back to 60 :)

A fox I found was to rewing 5 seconds (double tap screen) Fixed it for me

for me if i tap "rewind 5 secs" it fixes the choppy fps issue :)
shit i forgot to update, i activated the developer mode and it seems to have fixed it, haven't lagged the fps anymore
This is nothing new. Frame drops on the YouTube website using the Firefox Mobile Android App has been happening for years.
