[Bug 225520] [NEW] Firefox 3 proxy auto config (PAC) reload button does not work

[Hugues Fournier]

Public bug reported:

Binary package hint: xulrunner-1.9

The reload button in the network panel of Firefox 3 beta 5 has no effect.
This can be checked either by tcpdumping the request of Firefox, when clicking on the button, or by hosting locally a PAC file and watching the logs.

I have tracked it down this regression to the checkin upstream that
introduced the influence of http_proxy environment variable on our
systems on the proxy configuration of Firefox / XULrunner.

A new (intended) behaviour of nsProtocolProxyService::ConfigureFromPAC
was introduced in this checkin : ConfigureFromPAC exits early if the uri
is already known (this check was previously in other methods).

However nsProtocolProxyService::ReloadPAC (that is called by the reload
button) calls ConfigureFromPAC with obviously the same uri than the one
already known (otherwise this would not be a reload ;) )

Here is the patch I have submitted upstream :
