When you go to the font selection dialogue in Firefox:-
Edit - Preferences - Content - Fonts & Colours/Advanced
There's a horizontal line in the list of fonts you get to select when you click on the Serif, Sans-serif or Monospace selection bar. Does anyone know what this horizontal line indicates?
I originally thought the ones below the line might be the monospace fonts but that's obviously not right on inspection. Is it possibly that the ones below the line are bit-map fonts?
It would actually make selecting a font much easier if there was some sort of indication against each font to tell you whether it's a monospace or proportional font. Some are obvious but not all.
Also, a final question, there are fonts one can select called 'monospace', 'serif' and 'sans-serif'. Presumably if you use these then what you get is the system default which is defined somewhere in the build/distribution, there aren't actual font files with these names. Have I got this right?
