Can you attach a screenshot that show a problematic website?

• http://en.wikipedia.org/wiki/Screenshot

• Use a compressed image type like PNG or JPG to save the screenshot
• Make sure that you do not exceed the maximum size of 1 MB

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. If you have a font installed that covers this Unicode range then you may see a real (CJK) character and not the little box with the CSS code.

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).

Very frustrating. For once IE is working better than firefox!? Tried this: https://support.mozilla.org/en-US/kb/how-reset-default-user-agent-firefox -These instructions are inaccurate for 40.0.2 in several ways.

Thanks, cor-el! You are still rocking it... I sort of remember breaking this a while back when trying to fix intermittent variable monitor screen resolution. Just a passing comment- My laptop screen and monitor are different shapes. I wonder if Windows 10 would settle this.

Also looking forward to syncing firefox on computer and phone.
