Spell checking does not work with Outlook Web Mail in Firefox. This issue has been raised by many others but I find that the answers and solutions don't match my user interface and aren't really solutions. This seems to be a widespread problem and I really feel that Mozilla should solve it. Otherwise users like me will likely need to change browsers. - I am using the latest version of Windows 11 and Outlook Web Mail. - My Firefox is up to date (144.0.2) - Spell checking works if I switch to plain text. Thanks for any help with this matter. Mario
