Unfortunately, due to the constant willful or untested shenanigans of various website I have set up all my system’s Firefox profiles to spoof by default its user agent (and other JavaScript properties) as Windows 11, x86_64, Firefox LTS (even if I use latest, Aurora or beta). Some blantant recent example: YouTube uses lower quality options on browsers running on Arm-based systems — misreporting as an x86 CPU appears to be a widespread browser fix

Doing so has helped me and many friends/family I switched to a flavor of Linux (mostly Mint, but sometimes LMDE or Ubuntu or specific requirements/demands) avoid numerous dumb problems.

Even on mobile sometimes UX breaking issues creep up.
