"Black" tooltip problem Firefox: 1. Seemingly good workaround! 2. Where is "Colors — KDE Control Module"?

Indeed, that's familiar (although I thought I was the culprit myself by 
playing with some settings). After some experiments I found the point 
where to change it to make the tooltips readable. Start systemsettings, 
go to "Application Appearence" -> "GTK". Change the selection for GTK3 
Theme from oxygen-gtk to something else and click the "Apply" button.
