plenty of Firefox forks are still thriving and getting updates

download page has windows macos and linux

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

it’s one thing if they pay for them but if they are actually company devices that’s fucking weird

or host your own with nextcloud or casaos or the like
