I can only upgrade my extension by selecting the 'find updates' button
on the add-ons page and then running the upgrade. On my server I have
my upgraded xpi file and update.rdf. Is it possible to have the
upgrade\installation perform automatically without any user
interaction.

In reading other posts, they seem to mention using the mozilla AMO
site, is this the only way to perform an automatic upgrade
installation.
