plenty of Firefox forks are still thriving and getting updates

to my knowledge the anti cheat is basically disabled anymore

is it possible he forgot to select pro in the install menu a pro license will activate home no problem

should work just fine just look at the wiki for os-prober to get it in your grub menu

if your using grub you just need to install os-prober and re build your grub config and then you can boot windows from grub even on multiple drives
