how to get a hangout url from the hangout button?

PLEASE HELP! Facebook changed my url by it's self how to get number url back please?

• acebook changed my username by ITSELF and without me knowing it. I didn't do anything. Just went to my profile and facebook picked out an username for me from my name. WHY. Just me having this issue? All of my friends still have the profile.php?id=3892463284 etc. Why does facebook act by itself? I want the numbers back I never wanted a username, I don't want a username. How can it just change this all by itself? ANYONE find a way to get rid of the username and go back to the old number id url?

• Answer:

  I can't add anything to the previous comment, other than facebook settings don't just change themself, computers don't make mistakes, its normally the mistake of the user or programming which causes an error to occur, are you sure you didn't trigger a url name ( eg. setting up facebook email ) or maybe someone else did it by accident when logged into your account? But back to the original point, these settings cant be reverted, and don't change themselves.
