Switch it to value "false". It does not look like standard setting ony any built-in feature of Firefox, so this could be from some add-ons. Let's check add-ones, which are included and active in your FF. I found this (I didn't install it, but maybe it was installed by an admin).
Always on Top 184.108.40.206-signed.1-signed
Sets 'Always on Top' style for this windowVery simple "Always on top" addon implements the same simple functionality - it allows you to add style "Always on top" for current Firefox window.
You can use whether menu item, toolbar item or Ctrl-Alt-T shortcut
So turn it off, restart FF, and luckily work with it without being annoyed.
