Facebook sometime behaves in a “curious” way … they don’t let you export your email contacts but let Yahoo doing it …
So, let’s use Yahoo to make a backup of your friend’s emails.
- Create a Yahoo email account
- Click contacts in the left sidebar
- Form the contact toolbar, choose “Tools, Import”
- Click on the Facebook logo and authorize the sync
- Check the box on top near “Sorted” in the contact column to flag all contacts
- Form the contact toolbar, choose “Tools, Export”, and choose your favorite format (csv, mozilla ecc.)
- The download starts in seconds
Enjoy! : )
