Try with a new profile, and on a machine I was only able to reproduce it on the main page; not the videos sub-section.
Hope these help.

I was able to repro it with only one of the first couple of videos on https://www.reddit.com/r/videos. And reloading the page resulted in the same behavior. On most videos the icon disappeared right away, or got replaced with the loading circle. But on one video the icon stayed after the initial click and disappeared only together with the other video controls on the bottom of the video element.

Would be interesting if it's really caused by a regression in Firefox. I'm guessing this is more likely somehow related to YouTube's JS code.
