How to import your Facebook followers list and contacts into your Google+ profile

You'll need a Yahoo mail, and a Gmail account for this.

Broadly, the steps involved are, you first transfer your Facebook contacts to your Yahoo mail. Then transfer the contacts from Yahoo mail to your Gmail account. And from Gmail into your Google+ profile.

Here's what you need to do:
Log into your Yahoo mail account
Click on Contacts
Then click on Import Contacts
You should see the Facebook icon, click on it
Follow the instructions on screen, to connect Yahoo with your Facebook account, and begin the import of your Facebook contacts into your Yahoo mail account
Once complete, in your Yahoo mail account click on Contacts
Click on Actions -> Export All
And export the contact list from Yahoo, as a Yahoo CSV file
Save the CSV file on your desktop
Next log into your Gmail account
In your Gmail, click on Contacts
Click on Import Contacts
Select the Yahoo CSV file you saved on the desktop, and start the import process (ensure you import the contacts into a new group in your Gmail, to keep them separate from the rest of your Gmail contacts)
Once the import is complete, click on Contacts
Select the group of contacts which you've just imported
Click on More, and click on Export
Export the contacts list as a Google CSV file and save it to your desktop
Now log into your Google+ profile
Click on the Circles icon
Click on Find people
Click on Import address book
Select the Google CSV file you've saved to the desktop, and all your Facebook contacts will now be in Google+!
