Some emails, after opening, display a series of letters and numbers, etc., and some emails from other sources are displayed as they always have. I have updated to Firefox 102.0.2. Sometimes when I click on a particular email, the body of the email is not only a mess of alpha and numeric characters but the email that is opened is completely different than what I selected. In addition to this new problem, the screen display of my emails has changed; I no longer have an [Address] button across the top and when I access my addresses from a drop-down menu, they do not appear in the format they used to and the one I need.
