Why does Devise/Omniauth add garbage to the URL?

Question

After signing in with facebook, I'm being redirected to /#_=_, which shows the home page.

This sort of garbage also appeared in other URLs, for example when sign up failed and got redirected to /users/sign_in#_=_

Why does this happen, and how can I fix it?

Answer 1

If you really don't want it, some simple javascript and you're good to go :

if (window.location.hash == "#_=_") {
    window.location.hash = "";   }
