FB reference blends

[Haris1263]

Hey, I am to some degree perplexed about the correct arrangement of channels to join All facebook references into one.

In the wake of encountering different versions, not certain which one is correct and will work

A couple of transformations express that Search string should be - ^.*facebook.com$

besides, Replace string should be - facebook.com

While according to other Search string should be > .*facebook

likewise, Replace string should be - facebook keyboard ??

Generously control which one of this is correct and will work?
