There is probably a misunderstanding.  My main interest is to avoid
opening a second browser.  Assuming that Emacs has `Mozilla' first in
its list, and I'm running Firefox, browse-url ignores the latter and
starts a fresh Mozilla.  I would like this behaviour:

  . If browse-url-browser-function is customized to a specific
    browser, always use it.

  . Otherwise check whether there is a browser running -- I don't know
    whether it is possible to do that.  If such a browser is found,
    use it.

  . Otherwise, start a new browser, trying binaries in the order as
    specified within browse-url-default-browser.
