It's part of the "Merge duplicates" add-on - there is a "Mass Delete" option in there that lets you scroll through all your contacts and check the ones you want to delete.
Actually, here's what you can do:
1. Search for "Facebook", then click "Save to tab" in the top of the search results.
2. Go to Settings / Add Ons / Merge Duplicates (purchase this if you haven't already), then select "Mass Delete".
3. Click on the new Facebook search tab that was created in step 1.
4. Click through each contact in this tab, until all contacts have checkmarks next to them.
5. Click on Done, to get a confirmation of the contacts you want to delete.

Hi Nick,

Let me know if that helps.
