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.

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).

Thanks, working!cor-el said

Hello again, the Icons are now available.

But i have still Problems with some Fonts (screenshot).

Maybe there are wrong Settings ???

What font is used by Firefox on that page and what font is selected if you check that in the Inspector?

You can right-click on a web page and select "Inspect Element" to open the Inspector (Firefox/Tools > Web Developer). You can check the font used for selected text in the Font tab in the right pane of the Inspector.
