on certain websites some icons do not show up and just show a rectangle with a four digit letter and number code that starts with a letter. Does anyone know how to fix this? I have tried resetting the cache, looking for extensions that would conflict with these websites and have cleared them, and setting the minimum font size to be none. Help

I looked at the console of the website I was browsing and it gives me this error. Content Security Policy: The page’s settings blocked the loading of a resource at data:font/woff;base64,d09GRgABAAAAAIw4AB… (“font-src”). i hope this helps.

What hex code is in the little boxes? Is this in the E000-E8FF PUA range that is used for downloadable fonts?

Special icons are usually supplied by an icon font that is downloaded from the server (@font-face) You may see little boxes with the hex code of the character if you do not have a font installed that covers this Unicode range.

You can check gfx.downloadable_fonts.enabled on the about:config page and make sure it is set to true (if necessary double-click the line to toggle its value to true).


Such a font wouldn't normally be block by CSP rules.

Can you post a link to a publicly accessible page (i.e. no authentication or signing on required)?

If you use uBlock Origin then check the "block remote fonts" setting.


If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block content.

Firefox shows the shield icon at the left end of the location/address bar in case Content Blocking is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console about what content is blocked
