Created attachment 106524 [details] Firefox with breeze-gtk Hello. Fonts in Firefox menus and toolbars (tab bar, location bar) are rendered incorrectly. It seems font aliasing and hinting settings are applied incorrectly. Web pages seem to be rendered with proper font settings. I have Firefox-52 (current ESR). This happens both with GTK2 and GTK3 Firefox backends. This happens with Firefox addons disabled and a clean Firefox profile. Qt apps aren't affected, pavucontrol isn't affected either. If I change GTK2 theme to oxygen-gtk all fonts in Firefox are rendered correctly.

Cannot reproduce with a recent version like 5.20. Can you?
