I'm working under org-mode.
When I click on a [http://example.com] link, it opens a tab in Firefox as expected. The
.emacs config is:
'(browse-url-browser-function (quote browse-url-firefox))
However, for links in the form
file:///localdir/myfile.html it depicts the message
running /usr/bin/sensible-browser and starts Opera.
Why would emacs do that? Why does it not use Firefox or defaults to my system default browser?
