Who's it for?

MozBackup is for those looking for a simple way to backup and restore user profiles for Mozilla applications like Firefox and Thunderbird plus a number of other applications.

What problem does it solve?

As of early 2010 Thunderbird and Firefox provide no means for saving user profiles and data. There is no way to backup emails in Thunderbird. By using MozBackup the loss of emails, bookmarks and other important data can be avoided before a Windows upgrade or reinstall. The same user data can be backed up for redundancy. Email can be archived on a routine basis.

Standout features

  • Simple GUI: The screens are simple and easy to use. You are guided through the backup or restore process in wizard format.
  • Support for the following applications:
  • Profile Components: The following information can be exported or imported. Enabled components are dependent upon the selected application:
    • General settings
    • Emails
    • Address books
    • Bookmarks
    • History
    • Sidebars
    • User styles
    • Extensions
    • Saved passwords
    • Cookies
    • Saved form details
    • Downloaded file list
    • Certificates
    • Cache
    • Accounts settings only
    • Unknown files (optional)
  • Supports multiple profiles: Back up from and restore to one of many profiles.
  • Standard PCV format: The PCV files are in the ZIP format and can be opened by standard compression utilities. You may need to change the .pcv file extension to .zip.
  • Command Line support: The MozBackup Web site claims that you can run MozBackup from the command line but I was unable to get this option to work: see What's wrong? below. Example: "P:\Program Files (x86)\MozBackup\MozBackup.exe" "P:\Program Files (x86)\MozBackup\backup.cfg". You will need to create a config file (backup.cfg in my example).
  • User customizable settings: You can modify the \Program Files (x86)\MozBackup\backup.ini file to customize MozBackup:
    • Backup file name format (default is <application> <version> - <year>-<month>-<day>.pcv)
    • Backup directory (default is \Users\USERNAME\My Documents)
    • Number of monitors (default is 1)
    • Enable/disable prompting for password (default is true)
    • Compression level (0-9, default is 9 - maximum compression)
  • Support for multiple languages: 47 different languages are supported but vary by version.
  • Freeware: MozBackup is free for both business and personal use.

What's wrong?

  • Reliability: I experienced a backup that appeared to be empty and possibly corrupted. However, the error could have been mine so take that into consideration. I had also created a second backup to a flash drive that worked. I recommend creating two backups and saving one to removable media.
  • Saved profile replaces existing profile: If you restore a default profile all current default profile information, including emails and bookmarks, if applicable, will be replaced. Be aware of this if you have any emails or bookmarks that you don't want to lose. You can avoid this issue by creating a new profile and restoring the saved profile to the new profile name. Be very careful to select the right profile name! This is also useful for testing the integrity of the backed up profile and the restoration process.
  • "New profile" option does not work: I was unable to create a new profile using the New profile button on the Restore | Profile selection screen. Click the creating a new profile link above for a workaround.
  • Command line option fails: When using the command line option in Vista and Windows 7, I received a Cannot open file error.
  • Help file: There is no help available from the application. MozBackup is easy to use and you probably won't need help, but if you do, you can visit the MozBackup support page for help.

Bottom line
