Proxy and updates

I have tried updating FFP an TBP in the past with the automatic updates. I usually get the notification when I am at work. I connect through a proxy there. 99.99% of the time the update fails and hangs until I can manually update the entire program with one of your downloads.

Does the proxy connection have anything to do with updating?

If this is true it might explain all of the support topics that pop up after am automatic update is released.

Maybe FF of TB is handling portable media better, or maybe its just a coincidence that mine worked perfectly tonight for TBp 1.5.0.9 and FFP 2.0.0.1.
