I-Thunderbird Isithangami Sokwesekwa

My wife shares my computer with her own account and email address in Thunderbird. When she sends me an email, my name instead of hers is listed as the Correspondent. Can that be changed to her own name?

Attention: Toad-Hall Jan 18, 11:33:01 PM - - Many thanks for answering my first query: Have not tried any of your suggestions as yet, truth be told don't think I would be able to. My new query, between the time of asking my first question and receiving your email we somehow retrieved our emails, have no idea how this happened, however, we are now able to send and receive emails: My new query, can you help us retrieve our local folders. Thank you.

I have 2 email accounts on Thunderbird, a Yahoo account and a GMAIL account. Whenever I receive an email on either account, it appears as an email on BOTH accounts. This results in a completely duplicate list of emails on both accounts. My intention is for incoming emails to appear only on the account to which they were sent. How do I accomplish that? Thanks in advance for any suggestions!

I want to move TB from a win 7 machine on the C: drive to a win10 machine on the E: drive. I downloaded a fresh copy of TB to the win 10 machine and installed it in the D: drive. Completed set up and can send/receive emails. I copy/paste the profiles folders using a usb stick, putting it in the same folder on the D: drive as TB. However, TB doesn't see it. In Troubleshooting help, Environment variables, it clearly shows the roaming folder as C:, while the program is clearly D:. What have I done wrong and how do I correct it please? Screenshot of Environment variable below.
