Tor Browser and Unsafe Browser have no minimize & maximize buttons in the window titlebar
Regression in 5.8 (wb:b841a57a2e3b3d4752a73c974a75e3c5). I suppose that's because we run them as native Wayland apps, so they're responsible for CSD (client-side decoration).
It looks like Firefox tries to honor the system config regarding titlebar content:
git grep -E 'button-layout|gtk-decoration-layout'in the Firefox Git repo
Could it be that we block its access to said system config?
Workaround: both operations are accessible from the window list.
