Adblock+ with some lists, Privacy Badger, and NoScript can wipe all FB interference. A solid hosts file can also add one more layer to eliminate exposure to FB, Pinterest, and other fancy trackers.

Btw, yes it is easy. I have stopped using FB for so long that in order to log back in to delete my account they are asking me to be verified via "friends" (people I haven't worked with or talked to for years).
