Portal Home is displaying funny characters in Firefox
a colleague of mine has told me that when using Firefox Community Edition ESR 22.214.171.124 English, clicking the Alternate Home URL, the portal displays funny characters and some strange formation (see attached image). From "Need help finding.." down to the bottom, everything's displayed fine. This area of the characters usually is an empty space. All other tabs like work items, requests, search and others work and display as expected. IE 11 is doing fine also.
Me and another colleague do not have the issue either, but we're using the German version of Firefox. Obviously, this issue occurred after the last Windows security patching for February last week. OS is Windows 10. Does anybody have the same issue and knows how to fix it? Always using IE is not the solution for my colleague.
