Good evening.
For many years I have accessed my 4 talktalk email addresses using Thunderbird. My computer has just been converted from Windows 10 to Windows 11. I have had to reinstate Thunderbird and my 4 email addresses and this has been successful in all respectes back to normal, except that the address book is missing. Can you please advise me how I can copy my address book which is on my talktalk account so I can transfer it onto my new Thunderbird?
Many thanks.
