Why aren't web page nav icons showing up in my FF browser?

For some time now, I've noticed that small, thumbnail images -- particularly the small navigation icon images -- don't show up in my Firefox 34.0.5 browser (on a Mac, using OS 10.9.5). I've attached a small screen grab showing what appears, which is basically the image tag size box that is configured in HTML.

I'd love some help to understand this issue. Any suggestions are much appreciated. Thanks in advance!

Hello,

As I can see it is a narrow box with two rows of two characters? Firefox displays that code when it cannot find the corresponding character in any available font. The most common reason to see this is that some sites are now replacing image icons with font characters that Firefox has to download. If you have set Firefox to:

  • use only your preferred fonts instead of the page's preferred fonts
  • not download fonts (either in about:config or using the NoScript extension)

then you would need to change that in order to see the icons.

First check your font settings here:

"3-bar" menu button (or Tools menu) > Options > Content

Click the Advanced button and make sure there is a check in the box for "Allow pages to choose their own fonts".

If you change that, try reloading the page. Does Firefox load the missing icons?

If that doesn't fix the issue then do the following:

You can check the gfx.downloadable_fonts.enabled pref on the about:config page (you can go to it by typing about:config in your address bar) and make sure that it is set to true (if necessary double-click the line to toggle its value).

Hope it helps.
