When I open links, all I get are a string of little question marks inside diamonds like this: �. It also happens if I type in the URL of certain websites. Why?

When I open links, the new page or tab that opens only contains a long string of question marks inside diamonds - �. It doesn't happen with every link, and doesn't happen every time you open the same link. It also happens if I type in the URL of certain websites (or if I type in the URL for a link directly into the address bar).

It's only started happening in the last 3 or 4 days. Websites that I've stored in my favourites and have accessed through Firefox quite happily all year are suddenly only appearing as �������. Any ideas anybody?

Links should be stored as UTF-8 and show a little box with the hex code in case of problems and not such a FF FD code that indicates a character that can not be mapped.

You may have a corrupted font or a problem with an extension.

You can try to check the files with the System File Checker:

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

  • Don't make any changes on the Safe mode start window.
