I used to be able to 'Get new messages' by going File=>Get new messages File tab is no longer in top left of left hand side panel. How do I get new messages now...by the time they come through, the password I'm waiting for will time out. There used to be a tag...in the same drop down menu as above...to '''mark''' a message as eg unread or to "Tag" a message...this menu doesn't exist anymore, so how do I tag messages or mark them as unread Again...same menu...File => empty trash. How do I do this now? Is it possible to revert to the previous version of Thunderbird before this last update please?
