I’ve been using it on Linux for months and didn’t notice anything weird going on. It’s not my main browser though, so your mileage may vary.

No.

I use Firefox Focus ob iOS and AdGuard DNS.

Check out Helium. It’s what Brave was supposed to be. (And it uses Chromium.)

I’m running a 2018/2019 laptop I got in exchange from a friend around 2022 for an old TV and some cash 25€ or so. I doubled its RAM to 16GB a few years ago and it’s just fine. Im not paniny to upgrade it anytime soon. Three only moments I think about upgrading is when NVIDIA fucks up my Linux setup with their new drivers and I dream of switching to AMD instead of figuring out how to fix it.

I’ll probably keep on playing Shin Megami Tensei V: Vengeance and replaying Persona 5: Royal, although I’ve been craving some PS1 era game.

FF9 is totally worth playing back to back. I believe it’s the best entry in the series.
