392179 - RSS feed URL is malformed when adding it through url bar and using proxy auto-config (PAC)

Status: VERIFIED DUPLICATE of bug 367432

(Firefox Graveyard :: RSS Discovery and Preview, defect)

Description

[Martin Rasp]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.5) Gecko/20070713 Firefox/2.0.0.5
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; de; rv:1.8.1.5) Gecko/20070713 Firefox/2.0.0.5

When using a proxy auto-config (PAC) script and you want to subscribe to a rss feed by clicking on the rss icon in the url bar, the url will be malformed. I captured the request with wireshark and it looks like
"GET feed://http//www.heise.de/newsticker/heise-atom.xml HTTP/1.1\r\n"

If FF is configured to always use a proxy server (ip address, port) adding a live bookmark works as expected.

Workaround: The requested RSS feed has to be added manually or by entering its URL directly. 

Reproducible: Always

Steps to Reproduce:
1. Configure FF to use a proxy auto-config (PAC) file
2. Open http://www.heise.de/newsticker/
3. Click on RSS icon in the URL bar

Actual Results:  
The following error page is displayed:
ERROR
The requested URL could not be retrieved

While trying to retrieve the URL: feed://http//www.heise.de/newsticker/heise-atom.xml

The following error was encountered:

    * Invalid URL 

Some aspect of the requested URL is incorrect. Possible problems:

    * Missing or incorrect access protocol (should be `http://'' or similar)
    * Missing hostname
    * Illegal double-escape in the URL-Path
    * Illegal character in hostname; underscores are not allowed 

Expected Results:  
FF should open the popup window to add the requested live bookmark.

I've tested and confirmed this bug on the following platforms:

Windows XP, Firefox 2.0.0.3 - 2.0.0.6 - FAILED
Linux, Firefox 2.0.0.3 - 2.0.0.6 - FAILED
Linux, Firefox 1.5.0.9 - PASSED

Can anyone else confirm that this is a issue introduced into the 2.0 branch?

i see this with 3.0.8 on Gentoo Linux (x86_32) , and on windows 3.0.3-3.0.9

problem is when using autoconfiguration or configuration by url.

example of bad link:

feed://http//newsrss.bbc.co.uk/rss/newsonline_world_edition/front_page/rss.xml
