I have successfully migrated my profile from Mac to Windows. All of my stored emails and folders are present. I can receive and send email. There is just one problem. Thunderbird will not remember any passwords for the POP3 or SMTP server. When I migrated the Thunderbird folder to the Windows machine, I did as instructed and deleted the pkcs11.txt file. The first time I started up Thunderbird I used the command line with the -p option to make sure the migrated profile was use instead of the program defaulting to creating a new one. Like magic, all of my old emails appeared, exactly as they had been on the Mac. Great success. However, Thunderbird has not created a new pkcs11.txt file on the Windows machine. I am asked for the password everytime I check or send email. If I go into the Thunderbird preferences and look at the saved passwords list, it is blank. Everytime I enter a password I check the box to remember the password with the password manager, to no avail. What are my next steps?
