Running XP (SP3) - Not able to read some fonts on some websites
Fonts used on some pages become symbols, random letters and punctuation marks. (Ex: Yahoo.com)
When cut and past into another program they are readable.

Missing icons are usually supplied by a font that is downloaded from the server (@font-face) as you might see by little boxes that show the hex code of the characters instead. If you have a font installed that covers this Unicode range then you may see a real (CJK) character and not the little box with the CSS code.
Make sure that you allow pages to choose their own fonts.
- Tools > Options > Content : Fonts & Colors > Advanced: [X] "Allow pages to choose their own fonts, instead of my selections above"
You can check the gfx.downloadable_fonts.enabled pref on the about:config page and make sure that it is set to true (if necessary double-click the line to toggle its value to true).
Firefox 41 will allow icon fonts that use PUA code points to work with the font setting in "Options/Preferences > Content > Colors" disabled. When unsupported code points are used then you see the little boxes with the hex code.
