I have a very old computer with windows 7 and Thunderbird 11.5.14. 0 32 bit I have finally got a new computer with windows 11 and have installed Thunderbird 128.1 ESR 64 bit I tried to export from the old version but it will not install on the new version. How do I move my contacts from the old one to the new one - contacts are all I care about , I can get the email by logging in. There doesn't seem to be an export for just contacts. Im willing to put them in something like xcel as a csv if needed. thanks for any help. Dianne
