Process for Backing up Thunderbird Profile

Manually back up the Thunderbird profile

If you are comfortable with copying files and folders you can manually back up your profile. Backing up Thunderbird process can be as simple as copying a single directory to a backup location. Most of our time spends in searching where the profile folder is stored.

It’s a good idea to first get rid of any unnecessary files to reduce the size of your backup.

1. Firefox: ” Tools -> Options-> Advanced -> Network -> (under Offline Storage or Cached Web Content) -> Clear Now”

Thunderbird Clear Cache

2. Mozilla Suite/SeaMonkey: Edit -> Preferences -> Advanced -> Cache -> Clear Cache, as well as compact your mail.

3. Thunderbird: Compact your mail.

The simpl solution is to use Help -> Troubleshooting Information -> Show Folder to open your systems file manager at the current profile, and then copy/paste that directory somewhere safe. If your application doesn’t support that menu command see Profile_folder or Finding the profile folder on Windows to find where your profiles are stored. The profile which prefs.js file was modified most, recently is probably the profile you normally use.

A complete solution is: Backing up Thunderbird

1. Completely exit or quit the application. Mozilla Suite and SeaMonkey 1.x users on Windows should also exit Mozilla Quick Launch if it is enabled.

2. Find the “Mozilla” (for Mozilla Suite/SeaMonkey 1.x), “SeaMonkey” (for SeaMonkey 2), “Firefox”, or “Thunderbird” folder in the profile folder path that contains the registry.dat file or profiles.ini file and the “Profiles” folder (Windows and Mac) or <profile name> folder (Linux). See Profile folder – Firefox, Profile folder – Thunderbird and Profile folder – SeaMonkey for the location.

3. Copy the “Mozilla” “SeaMonkey” “Firefox” or “Thunderbird” folder to the backup location. This will back up all profiles in the default location and the “registry.dat” or “profiles.ini” file that keeps track profiles.

4. If you have created any profiles in a custom location, copy them to the backup location and make a note of the original location.

5. Mail is stored by default within the profile. If you re-configured Thunderbird, Mozilla Suite or SeaMonkey to store an accounts messages outside of the profile, you need to also copy the “local directory” for that account. Look in Account settings to find the location of each account’s local directory.

To restore a profile backup:

1. Close the application whose profile you’re going to restore. If you’re using Mozilla Suite or SeaMonkey 1.x you should also exit Mozilla Quick Launch if it’s enabled.

2. Copy each folder you backed up to the exact same location that it was in when you made the backup.
