Is Firefox installed as a snap package on PopOS? That could be it if that’s your only snap package. I’d recommend installing a Firefox fork that’s a regular deb package (Libre Wolf probably?) and seeing if that changes anything

Lmao isn’t Mint based on Ubuntu also? If you’re going to suggest switching distros entirely for slow loading on a single app might as well choose one that’s not derivative

Arch is like buying a Lego and putting it together versus an action figure. If you don’t enjoy putting together the Legos then what’s the point?

You should probably go with a ready to use distro

Don’t forget learning about systemd and then immediately deciding you actually don’t like it and would prefer something else
