hardly readable, white on very light grey

## observation

See attached screenshot

## expected result

readable text :-)

## further information

I am running openSUSE Leap 42.2 with awesome as window manager and a current
firefox installation. The same observation could be confirmed by other people
in different environments, e.g. also within a full gnome session. Also it is
not restricted to firefox this is why I assume "gnome" is the right component.
