607262 - Failure to load PAC file

Status: RESOLVED INCOMPLETE

(Firefox :: General, defect)

Description

[leE]

User-Agent:       Mozilla/5.0 (Windows NT 5.1; rv:2.0b6) Gecko/20100101 Firefox/4.0b6
Build Identifier: Mozilla/5.0 (Windows NT 5.1; rv:2.0b6) Gecko/20100101 Firefox/4.0b6

If I configure a location of a PAC file for automatic proxy configuration it fails to load.  This causes the browser to attempt to contact websites directly instead of via a proxy.

I have used WireShark to ascertain if the file was ever loaded or if it was purely not parsed properly, and I can confirm that the file was never loaded in the first place (it does work in Firefox 3.x, IE7, IE8).

The file is located on a fileserver and so is addressed in the format:

file:////fileserver/share/pacfile.pac

Reproducible: Always

Steps to Reproduce:
1. Configure use of a pac file for auto proxy configuration
2. Start Firefox
3. Attempt to browse to any site
Actual Results:  
A DNS request is sent out (confirmed via wireshark) and firefox attempts to connect to sites directly.  If no direct access is available (i.e. access via proxy only) then this will eventually time out.

Expected Results:  
A website should successfully load.
