295433 - Starting Firefox while configured with an Automatic Proxy fails to open browser start page

Status: VERIFIED DUPLICATE of bug 100022

(Firefox :: General, defect)

Description

[Drew J. Como]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050523 Firefox/1.0+
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b2) Gecko/20050523 Firefox/1.0+

(Possible reference bugs: 260884 and 279161)

Within the nightly builds of Firefox as well as the 'Deer Park' builds, if an
Automatic Configuration Script is being used, the URL set in the 'start page'
area fails to load upon initial open of the browser.  (Firefox times out.)

Reproducible: Always

Steps to Reproduce:
1. Block all TCP Port 80 direct connections from the test workstation on a
firewall, however allow the proxy to connect.
2. Set a proxy within the Automatic Configuration Script area and set the
browser's homepage to a site such as www.google.com, etc.
3. Close the browser and then re-open.
Actual Results:  
You will see that the initial connection that is made from Firefox tries to go
direct to TCP Port 80, rather than sending the connection over the proxy.  This
will ultimately fail since TCP Port 80 outbound is blocked.

If you click the 'Stop' button and then re-send the request via the address bar,
the connection is forwarded over the proxy correctly.

(This appears to have been broken recently, since the official build of Firefox
1.0.4 does not seem to exhibit this behavior.)

Expected Results:  
Send the initial connection over the proxy, which would result in the page being
displayed correctly.
