I don't thik so. I didn't change the default behaviour, which stay like
for the other browsers. But I added a possibility, which I think, make emacs
better than the other browsers.

Actually, the only way to browse an URL reusing the same Emacs window is
to define another `brows-url-emacs' duplicating this one.

I think it's just sad this possibility wasn't allowed because others
browsers aren't able to do it.

I don't know a way, for the others browsers, to reuse the same window /
tabs / whatever to display another url. This is, I think, the reason of
the comment. Maybe I should then add a comment to state this more
clearly ?

#+begin_src emacs-lisp
;; With all other browsers the URL is always shown in another window
;; than the current Emacs one since it's shown in another application's
;; window. But, here we can control that, so let's have the choice !
#+end_src

What do you think ?

And I didn't thiks about this : but should I add something in NEWS ?
