My guess was actually about how it handles garbage collecting canvas buffers when using texImage2D. Since the Skater game uses multiple fullscreen canvases, it might be more noticeable than Mine Blocks or Hexagon Tribute, which I think only use one. But optimizing that didn't have an affect unfortunately, so I'm not sure.

While working on the next project, I thought I found a big optimization for Firefox, but unfortunately it didn't make a difference when applied to Skater Without a Crown. I'm not sure what's so off about that game to cause such weird issues in Firefox.

My subscriber count had been roughly the same for so many years that these numbers still aren't making sense to me haha. But I'm not complaining, this is awesome!!
