I've had issues running web games in Firefox (EDIT: even after disabling extensions), but Brave will run them fine. No, I haven't compiled a list. I prefer downloading and playing locally, so usually do that if available.
Damn that's weird I wonder what Firefox does that other game don't I don't know nothing about tech usually, but I know you can change things in FF about:config, maybe some kind of settings would fix things, but I'd had to know what even causes the problem in the first place lol
