 the user wants to do immediately instead of what the browser will do
 later?

 the current browser window is closed (this does not spawn a new Firefox
 process, only a new window)."

 feedback for users to explain that the action has been done?

 Copying part of my comment in comment:16:ticket:27511 over for posterity:

  I think that comment makes sense to me. I am totally fine with renaming
 that feature as "New Identity" might be a concept that's too hard to
 grasp. So, anything that's easier here to understand and does the same
 under the hood is a win in my opinion.

 For the remaining dev questions:
 1) ephemeral tabs: that could be an idea but we should discuss it in a
 different ticket, not one related to new identity as I would assume both
 might live together in the browser (i.e. the ephemeral tabs would not
 replace New Identity)

 2) New Identity on TBA: Yes, TBA should replicate the behavior as we have
 it on desktop (although that's not relevant for this bug)

 3) New Identity without closing the window: I am afraid it's already hard
 to get rid of all browser state the way we are doing it right now. So, to
 be sure we get rid of all window state the only option we have so far is
 closing the window and create a new one. We might get away from that
 requirement if we audited all the relevant parts properly but that's a
 tricky task and would definitely be something for a new ticket.
