One of my email providers performed a maintenance routine. Subsequently I was no longer able to select the font type when composing an email. Oddly the source code for the composed email displays the font type I selected but the text displays in the email as arial only. The email provider checked my account and could not find any problem. They could select and print out the various font types. They assume the problem is with the browser (Firefox). So, here I am with no solution. Does anyone have any ideas how this problem might be corrected? Would uninstalling - re-installing Firefox work? Should some setting be changed, etc.?
