Use system proxy settings does not work

[grofaty]

Today I have installed Firefox 3.5 beta4 (Shiretoko) using the following tutorial http://webupd8.blogspot.com/2009/03/install-firefox-31-beta-3pre-in-ubuntu.html (replaced jaunty in repository name instead of intrepid).

I started Shiretoko and I can access all local web servers. But when accessing web pages that must go through proxy server page is not loaded and no error is displayed. In status bar there is just info "Waiting for.... server name" and then no page is displayed.

I use proxy server settings from: System | Preferences | Network proxy and browser proxy is set to Edit | Preferences | Advanced tab | Network tab | Settings | Use system proxy settings.

Workaround: If I manually change settings Edit | Preferences | Advanced tab | Network tab | Settings | Manually proxy configuration and manually enter proxy server settings then Shiretoko works normally as it should in the first place.

By the way I have also firefox 3.0 installed (default jaunty install) and settings in browser is Edit | Preferences | Advanced tab | Network tab | Settings | Use system proxy settings. And Firefox 3.0 is working fine.

It looks there is some bug in "Use proxy server settings" option in Shiretoko.

P.S. Sorry I can't sent apport info (ubuntu-bug report) it just produces some error in Jaunty, but works fine in Intrepid.

Additional info:
1. lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04

2. apt-cache policy firefox-3.5
firefox-3.5:
  Installed: 3.5~b4~hg20090330r24021+nobinonly-0ubuntu1
  Candidate: 3.5~b4~hg20090330r24021+nobinonly-0ubuntu1

3. I expected to see web pages when internet web pages are accessed and Edit | Preferences | Advanced tab | Network tab | Settings | Use system proxy settings option is used

4. Instead in status bar there is message "Waiting for server_name" and then after few second no error is displayed and no page is loaded - blank page.

Hi,
now I have removed Shiretoko 3.5b4 using command: sudo apt-get --purge remove firefox-3.5

I have downloaded file firefox-3.5b5pre.en-US.linux-i686.tar.bz2 from latest trunk mozilla web page:
http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-mozilla-1.9.1/

I have untar file and run program. From Help | About: "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1b5pre) Gecko/20090429 Shiretoko/3.5b5pre"

I have check settings Edit | Preferences | Advanced | Network | Settings | Use system proxy server and try to access internet web site and it works fine. It looks like this bug was fixed in one of the next release of firefox.

Regards
