El Presidente:
Hi and welcome! While I haven't touched Firefox in more than a year, I can tell you what I remember. First, frame rate was considerably worse for me with many units on screen compared to Chromium-based browsers. This was purely webgl/gpu related. Second, there would be drops with large armies being commanded, which would be induced by high CPU usage. The game loop is single-threaded btw. I remember profiling and everything would just take much much longer than it would in Chrome on the same replay file. It's true that my code isn't well optimized to begin with in terms of memory and data locality, but on Firefox performance simply degrades faster and worse than on Chrome. On Chrome you'd have to play Rekoool to begin having problems or maybe play on a mobile phone with a lower CPU frequency. On Firefox, I would notice issues even on desktop. Last, OPFS performance was abysmal at the time that I last tested it (10x slower than Chrome). You can try the test page at https://use-strict.github.io/file-system-access/example/test.html and see what I mean.
