Sometimes a problem with Firefox may be a result of malware installed on your computer, that you may not be aware of.

You can try these free programs to scan for malware, which work with your existing antivirus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP if you don't already have one.


Further information can be found in the Troubleshoot Firefox issues caused by malware article.

This can be a problem with the font that is used to display the text.

You can right-click on the text and use "Inspect Element" to open the built-in Inspector and check the Font tab to see which font is used.

You can use this extension to see which fonts are used in text that is selected (right-click: "Show fonts in selection").

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

You can try different default fonts and temporarily disable website fonts to test the selected default font.
