Bazzite has been astoundingly good for me. The only games that have issues are usually those with kernel-level anti-cheat and tbh I wouldn’t play those anyways if I was running Windows (although I understand that’s a deal breaker for some).
Support for Bazzite is fantastic too. Kyle and the rest of the folks on Discord are amazing!
Pretty sure with Firefox on Android you can install extensions. Should be able to use that, no?
