Hi

You user data will not automatically move across to your new PC, so I recommend that you create a backup of your Firefox profile and move that across to your new computer.

I recommend you have a read of this article that will walk you through how to back up and restore information in your Firefox profile.

I hope this helps, but if not, please come back here and we can look into a different solution for you.

Note that Firefox (browser) and Thunderbird (email client) are different applications and have a separate profile folder to store your personal data.
