(Firefox :: Settings UI, defect)

Firefox/1.0.2

I searched for bugs but can't seem to find the exact problem. I use to ISPs to
connect to the internet, one that is direct connection and one is through a
proxy server. Ideally when I set the option to Auto Detect, I can always browse
the web pages whichever connection I use.

However, if I set the browser to Auto-Detect Proxy settings, and I connect to
the internet using the ISP that requires proxy to connect to the internet,
Firefox still behaves like it is connecting directly to the internet instead of
connecting to the proxy first before using that to connect to the internet.

Note that this is not just an ordinary proxy for anonymous surfing. Instead,
requests have to pass this proxy server before going to the internet.




Reproducible: Always

Steps to Reproduce:
1. You need a connection that uses a proxy server to connect to the internet. It
means that if the proxy server is down, you cannot access the internet
2. Access the internet with the options Auto Detect Proxy settings
3.

Actual Results:  
Cannot access internet, status bar actually shows "connecting to yahoo.com"
immediately

Expected Results:  
Should be able to access internet, status bar should show connecting to
xxxx.xxxx.xxx(proxy server) before connecting to yahoo.com

Comment 2

can you please provide precise steps to setup this autodetect option in firefox?

Comment 3

[Kerwin Ramos]

ok,
go to Tools - Options - General tab, Connection Settings, then check the
Auto-Detect proxy settings for this network

Does your ISP support WPAD (Web Proxy Auto-Discovery)?  Does this work in IE?

Comment 5

[Kerwin Ramos]

I'm not sure WPAD since this ISP is for my office.
It does work with IE though. My analysis is that IE uses the connection settings
for each dial-up account so it does not encounter this connection problem. I
think the fix for this is just to have firefox check the settings of the dial up
account you are using and use that settings if you have the Auto-Detect setting
option selected.

[Mike Connor [:mconnor]]

There's a bug on using per-dialup account settings elsewhere, but this as
reported is probably INVALID.

Comment 7

[Kerwin Ramos]

i don't think this should be counted as invalid unless you have really been
unable to recreate this problem. as I have said, all you need is an ISP
connection that needs a proxy to connect to the internet. no proxy, no internet
access kind of scenario. What I really mean is Auto-Detect proxy settings does
NOT work at all if you use proxy to connect to the internet rather than a proxy
that makes anonymous surfing.

This is reproducable for me as well. I have to restart Firefox when I'm switching locations -- work->home and vica versa (I'm laptop user and I usually suspend at one location and resume at another).

In the office I do have proxy with usernam/password authentification and it gets auto-detected but only when I restart Firefox.
Back at home I do not have any proxy.

I guess that Firefox should remember the IP address that was used while auto-discovering proxy and if this address changes, do the auto-discovery again.

sorry for bugspam, long-overdue mass reassign of ancient QA contact bugs,
filter on "beltznerLovesGoats" to get rid of this mass change
