Confirmed on 66.a01 from Dec 12. Also toolbar buttons don't appear in the top left area.

Interestingly, it does not give the same issue on 100%, 125% or 200% display scale factor (configured via Gnome display settings), only an issue on 150%.

I've tested this report on Ubuntu 18.04 using the latest Nightly, Beta and Fx release builds. However, I could not reproduce the issue. I will try to install Arch in order to reproduce. Please change if this is not the right component.

The bug has a release status flag that shows some version of Firefox is affected, thus it will be considered confirmed.
