Manual profile backup

My steps:

• Modify %APPDATA%/mozilla/firefox/profiles.ini to point to a new default profile (empty folder)
• Install Firefox, run it once
• Exit Firefox, the new profile is now populated
• Copy over the following files from old profile to new
  • bookmarks.html
  • cert8.db, secmod.db, key3.db, signons.txt
  • cookies.txt, hostperm.1
  • mimetypes.rdf
  • user.js, prefs.js
