i am having an issuse with my email disappearing after its read and i leave the inbox and go to another folder. If "Read" Emails are left in the "Inbox", then I leave that folder, move to another folder, and return to the "Inbox" only "Unread" emails are visible. All the "Read" emails previously in the "Inbox" have disappeared In his response here, https://support.mozilla.org/en-US/questions/1174396, Matt says click View>Messages>All but I dont see a View>Messages option unless I am not looking in the correct place. On the Menu, I select the View dropdown and only see: Toolbars, Layouts, Folders, Today Pane, Calendar, Tasks, Sortby, Threads, Headers, Message Body As, Display Attachments Inline, Zoom, Text Encoding, Message Source, Message Security Info. There is no "Messages" option available. I have been having this issue since around the time of the last update. Am I missing something here? Any help would be greatly appreciated. Using 64bit Windows 10. Thanks.
