Remove 1 friend on fb who has deactivated their account

HERE IS THE ONLY SOLUTION IF YOUR FRIEND'S ACCOUNT IS "DEACTIVATED" it appears in blue in the friends list: "A LEFT DOUBLE CLICK" on the friend whose account is deactivated, a first window titled Inactive Account will appear with the following message: "This account has been deactivated. Only you can see DUPON on your friends list. You have the option to unfriend DUPON." At this point, click on: "UNFRIEND DUPON" which appears in blue compared to the rest of the message. A second window will appear asking if you really want to remove DUPON from your friends list. You just have to click on: "REMOVE FROM FRIENDS LIST" and your friend's deactivated account will disappear permanently from your friends list. Don't thank me, haha lool

Regarding deleted accounts that appear in black in the friends list, there is no possible solution as of today.
