I recently changed my system's color settings and now the text boxes in Firefox are dark grey. This is fine when the text happens to show up as white, but when it shows up as black, I can't read what I'm typing. (I'm not clear on what makes the difference. The box I'm typing this in now happens to be dark grey with white text.) I've tried playing around with settings within Firefox preferences and in my OS' (Kubuntu) system settings, and haven't yet been able to identify what settings exactly might change this specific aspect.
