问题
I'm using AngularJs 1.4 with ngFacebook module. Why after every login Chrome browser adds new entry in "Resources -> Images"? What else should I do in my logout function? Currently I only clear localStorage, but do not call ngFacebook's logout. Doing the later will force the user to enter username/password again.
