When you create, rename, or delete a profile using the Profile Manager, the information stored in this file is updated. They look in the profiles.ini file (Firefox, Thunderbird, and SeaMonkey 2) or in the "registry.dat" file (Mozilla Suite/SeaMonkey 1.x) to find what profiles exist and where they are located.
FIREFOX PROFILE MANAGER HOW TO
Mozilla applications don't know how to discover a profile by just looking in the default location where profiles are stored. In such cases, you can update the information stored in the prefs.js file by using the "Browse" button for the local directory in your Options/Preferences for (Mail & Newsgroups) Account Settings -> Server Settings and (Mail & Newsgroups) -> Account Settings -> Local Folders to specify the correct account and mail directories. Thunderbird and Mozilla Suite/SeaMonkey, for example, use the same format to store messages and address books on all platforms.
FIREFOX PROFILE MANAGER MAC OS X
Note on moving profiles between operating systems: If you move your profile between dissimilar operating systems (Windows to Mac OS X for example) the path names in the prefs.js file (your settings) may have the wrong syntax. If you're using Thunderbird, you may find Moving your profile folder - Thunderbird easier to follow, since it doesn't cover multiple applications as this article does. If you're migrating from Windows to Linux, you may find Moving from Windows to Linux more useful. However, you may find it easier to share a profile if you move it first to a location whose path doesn't depend upon the user name.

In this case you don't physically copy the profile since you're just updating another user's profiles.ini file to use the same profile. Configure another operating system account to use the same profile.Manually restore a profile backup after reformatting the hard disk.
