Firefox does not display application icons. Instead I see small box outlines.

When I run an online application, such as Horde Mail, I see no buttons, nor words that are clickable. Instead I see a small box where the button, or clickable-word, should be. The small box is rectangular, is in outline, and has four tiny characters in the middle. What are these? How do I convert them to the buttons they are supposed to be?

Chosen solution

Those missing icons are actually supplied by a font that is downloaded from the server (@font-face) as you can see by the little boxes that show the hex code of the characters.

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).

Make sure that you allow pages to choose their own fonts.

I should have said, that all of the sites which have problems, worked fine for years. This behavior only began a couple of months (weeks?) ago.

Thanks so much. This was really bothering me. It was the "Allow pages to choose their own fonts, instead of my selections above". I do not remember doing that, although I must have. Thanks again.
