Since updating Firefox, just about every window I open uses a script font that is very small and unreadable -- why, and how can I get it to use normal fonts?

I never had this issue before the last update I made. The font is a font on my computer and I thought that maybe it was the font and if I disabled it, the problem would go away. But sadly, it just picks another fancy script installed on my computer. It doesn't matter how many I disable, Firefox continually picks another fancy script to replace the ones I've disabled. What's odd is that some windows I open are almost entirely the fancy script and others may only have one line or a heading in the script. This is not an issue at all on Safari and was never a problem on Firefox until the next to last update I made.

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


You can do a font test to see if you can identify corrupted font(s).

You can also try different default fonts.

  • Firefox > Preferences > Content : Fonts & Colors > Advanced
  • [ ] "Allow pages to choose their own fonts, instead of my selections above"
