This can be restored afterwards on same Windows’ machine or some other one though. One can make use of MozBackup to also backup & restore Firefox profile, Mozilla-Suite profiles, and even Netscape 7 profile. But this tool come with certain merits & demerits. While backup up data users face certain issues like, they cannot backup using MozBackup or errors like: Mozbackup Cannot Open File

  • When looked inside that unzipped folder, address books, mail folders, as well as some other files could be seen, which make up the profile folder
  • One can also try restoring or migrating that unzipped profile-folder manually
