Has Thunderbird changed how you transfer your profile?

No email problems, but I am looking to transfer my email credentials to another computer that I have.

I know the old way used to be dropping your profile folder under \AppData\Roaming\Thunderbird\Profiles\(your profile folder's name), but now I've heard it's "automated" and you now have to go through each and everyone of your email accounts and enter your username and password for each one. That Thunderbird will no longer recognize profile folder changes, even if you're logged in as an admin to do it.

Can somebody confirm when this happened?

Thanks
