Fresh Thunderbird (115.7.0 (64-bit)) install on windows 11. Set up my POP3 (x4)accounts okay, but missing any form of the address book. When I click on "Tools" > "Address Book" , or hit CTRL+Shift+B nothing happens. The program is grabbing email addresses as when sending new messages I get the contacts button with previously used addresses, but no actual address book that I can add/edit addresses. I did try un-install and re-installing thinking i just had a bad install. The second issue is that Thunderbird is no longer automatically retrieving emails on startup, even though I have the option checked for each email account. It is retrieving on the 10 minute intervals that I've set it too, but not on startup. I'm a long, long time Thunderbird user, this is the first time I have ever had any issues. Any help would be much appreciated. Cheers
