''Came here after a response on my google play review.'' The problem is exactly as the title describes. Playing videos on various websites, such as Youtube, Vimeo, Twitter and Reddit for example, on firefox mobile (including firefox focus) results in the videos playing back with low fps instead of their native fps. Refreshing the page the video is on '''sometimes''' fixes the issue, than once you pause the video and resume it the problem with the low fps shows up again. Reinstalling doesn't fix it and downgrading to an older version made the problem occur less, but videos would still sometimes play back with low fps.
