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

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).

problem is tools, etc. represented by hex blocks and when you type in address bar or search bar you type in hex blocks.

ok. loaded firefox by "run as administrator" and everything normal. went to about:config and gfx.downloadable_fonts.enabled was true. under tools, etc. "allow pages to choose their own fonts, instead of my selections above" was checked. weird.

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

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.

You can use the System File Checker to check for missing and corrupted font files. It needs to be run from an Elevated Command Prompt. Open a cmd.exe window as Administrator: Start, click Programs, click Accessories Right-click Command Prompt, and choose "Run as administrator" Click past the UAC Screen After the cmd.exe prompt, type: sfc.exe /scannow and press Enter

Try to disable OMTC and leave hardware acceleration enabled to see if that works.
