Hello nguyenhuu194, nobody can attach a screenshot in the first question, the only way to attach the screenshot is by clicking the Browse... button below the Post your reply box.

thank you

Missing icons are possibly 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).

Tell me why this occurs and how to fix it?

Can you help me.? Please see the attachment.
