You can do a check for corrupted and duplicate fonts and other font issues:

I don't think it works ... the fonts doesn't change but I think the problme is in shadow of fonts ... I guess ! I removed all fonts but it didn't work. look to the picture and you will understand ...

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).

In Firefox 4 and later Safe mode disables extensions and disables hardware acceleration.
Try to disable hardware acceleration.

  • Firefox > Preferences > Advanced > General > Browsing: "Use hardware acceleration when available"

If disabling hardware acceleration works then check if there is an update available for your graphics display driver.
