Scaling Issues After Update To Firefox 103

I just updated to the just released Firefox 103. The whole application appears too large on my 4K display. I did not have anything similar yet. Any ideas?

Update: the issue did not appear on my 1080p laptop.

Hello! Thanks, that did the trick. Question is why that value ended up at 1.5 after the update :face_with_monocle:

Anyway, problem solved.
