Manju:  What extensions, if any, do you have installed?  Do you see the same
behavior with a new, clean profile (run "firefox.exe -profilemanager" and create
a new one and try to reproduce).

How long has this been happening? Did it start before or after you installed 1.0.3?

Does it keep happening even after shutting down and restarting the browser?
After you log out of your account and/or shut down and restart your machine?

Do you have any extensions installed? If so, which ones?

If you have extensions installed, does the problem persist if you start the
browser in "safe mode"? That is, from the command line use the -safe-mode
argument to launch without any extensions.

Could it simply be that he's got that URL in his clipboard and middle clicking
is loading it?

I've seen this before many times.  Most of the popular desktops will save the
contents of your clipboard across login session.  This means that whatever
nonsense you happen to have in your clipboard, will either load the URL, or do a
google search and bring the user to the first hit.

A good example to try is to copy "http" into your clipboard, then middle click.
 It will bring you to www.microsoft.com if you have google as your default
search engine.  This caused me much confusion several months back.
