Nvidia here under Linux, been running Nvidia hardware/drivers for about five years now with little in the way of problems. The latest hardware is supported on release, and my performance while gaming is fantastic.
Even Wayland support is maturing under Linux running Nvidia hardware/drivers, to the point whereby it's mostly as usable as Wayland gets now.
At least you have the option of running the latest Nvidia hardware under Linux, it seems dedicated GPU support under MacOS is dwindling by the month.
I never stopped using Firefox, and I never had a problem with anything but Government sites.
