[Firefox] How to backup and restore important data

BACKUP

  1. Head to C:\Users\%USERNAME%\AppData\Roaming\Mozilla\Firefox\Profiles\
  2. Copy/Backup the directory in some place safe

Do you have multiple directories? that means you have multiple Firefox's profiles, in most cases xxxxxxxx..default is the main one (if you have multiple Firefox's profiles, you are pro user, what the hell you doing here?!)

RESTORE
