User-Agent:       
Build Identifier: Mozilla/5.0 (X11; Linux x86_64; rv:2.0b8pre) Gecko/20101122 Firefox/4.0b8pre

The first access to an FTP-URL bypasses the Proxy-Settings of an Automatic Proxy Configuration file at least if the URL is given on the command line or is opened from a bookmark.

Reproducible: Always

Steps to Reproduce:
0. Copy attachment "proxy.pac" to /tmp.
1. Open FF with fresh profile
2. Edit|Preferences|Advanced|Network|Settings|Automatic Proxy Configuration URL
   := "file:///tmp/proxy.pac"
3. ensure that nothing is listening on 127.0.0.3:23111
4. close FF.
5. On the command line execute: "firefox ftp://xmlsoft.org/libxslt" -> (1)
6. Bookmark the URL
7. Restart FF, click on bookmark -> (2)
8. Click again on bookmark -> (3)
Actual Results:  
(1), (2) FF connects directly to the ftp-server and renders the directory content.

(3) "The proxy server is refusing connections"

Expected Results:  
(1), (2), (3) "The proxy server is refusing connections"

Happens with mozilla-central from today and also with 3.5.15

This bug was reported using a pre-release version of Firefox 4. Now that Firefox 4.0.1 final has been released, can you please update and retest your bug? A fresh profile would be a good starting place to test,

We had some changes in the pac handling, does it still happen with Firefox18beta or later builds ?

Comment 5

I can't test it due to Bug 723487:

XPCOMGlueLoad error for file ...firefox-18.0b6/firefox/libxpcom.so:
libxul.so: cannot open shared object file: No such file or directory
Couldn't load XPCOM.

Nonetheless I would like to test the changes. Which commits/bugs implement them?

A possible incomplete query http://bit.ly/Vu0WIe
One rason why this bug report didn't get much attention is that it got never moved into the right component....

The issue is back again in the 17.0.6esr version not only on FTP but also on HTTP and HTTPS. (was never fixed in 10esr or 17esr)

firefox-20.0a1-2013-01-11 does not show any of these issues.
