new thunderbird upgrades have messed up my inbox
Recently Thunderbird is not displaying new mail in inbox. It shows in my webmail service. It shows if I make a selctive search. It shows in notifications. All new mail does not show nut one or two may. It's just inconsistenct. I have tried the suggestion of re-indexing from the Thunderbord option to do that.

Perhaps you missed the transition to threaded email which placed emails on the same thread together in the mail list. Those mails when the thread is collapsed are shown with an underline instead of bold. See https://support.mozilla.org/en-US/kb/message-threading-thunderbird#
