How to recover lost email accounts in Thunderbird

Ivan Radovanovic's picture

This is how to handle situation when Thunderbird wants to do set up from scratch after it crashed. First locate profile folder - you can do that in Thunderbird by using Help -> More troubleshooting information. Once you locate this folder looks for prefs.js and possibly prefs-1.js, prefs-2.js etc.

  • Turn off Thunderbird
  • Backup old prefs.js (just in case this doesn't work)
  • Find the most recent of these prefs-*.js files (most recent in sense of modification time)
  • Copy most recent prefs-*.js into prefs.js
  • Start Thunderbird - if everything went well you should have all your email accounts again
