*** Firefox; that is, the version bundled with the Tor IM Browser
package, running from a USB stick. I have attached a screenshot of
the warning message. I have no idea what is the application that
would be launched. I can send you the link to the file if you'd like
(the file is encrypted and about 800 KB).

*** Yes, that is what I thought. Is there a way to tell the portable
Tor-enabled Firefox browser, "always use me and don't launch any other
browser"? Otherwise, wouldn't any request made through another
browser completely bypass the Tor circuit? That would be an
especially serious problem if the default browser installed on the
host PC was Firefox, since it would be easy to assume that you're
routing all your requests through Tor, when In fact they're being sent
through the non-Tor host-installed Firefox browser.

*** Thanks, that makes sense.
