Moving Mozilla Thunderbird to a New Computer

Thunderbird’s email account settings are all stored in the user’s profile folder. To get the whole setup back, just copy the profile folder from the old machine to the new one.

For me, my email storage location still had the same path, so there was no issue with the actual emails themselves.
