Changing the Fonts in Firefox

Posted on April 17th, 2008

Changing the fonts in Firefox, why would someone want to do that ? Maybe because of the same reason someone changes Windows system fonts, maybe because the fonts that are displayed are not optimal for his display setting, say Clear Type. I recently ran into a problem that Firefox was displaying text in forms so stuffed that it was impossible to read, even when changing the size of the font .

It’s obviously better to use Clear Type fonts if you use a LCD monitor and have Clear Type enabled. Firefox by default uses Verdana and Arial I think as Serif and Sans-Serif fonts and another one for Monospace. The Monospace font was the one that was causing the troubles for me, here is a screenshot of the font setting in Firefox.

And here are some examples of how fonts change the display of text on websites. JPG is a lossless format and results might look different on your computer. The best option would be to test different fonts to see which works the best in your environment.

You can access the font settings in Tools > Options > Content Tab > Advanced Button.
