221772 - Thunderbird does not support proxy username authentication

Status: RESOLVED DUPLICATE of bug 205947

(Thunderbird :: Mail Window Front End, defect)

Description

[Bruno Bestel]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.5a) Gecko/20030728 Mozilla Firebird/0.6.1
Build Identifier: Mozilla Thunderbird 0.2 (20030901)

This seems to be another part of the bug described in 216407 (automatic proxy
configuration). When Thunderbird is configured in manual proxy configuration
with a proxy which required username authentication, and the "Block loading of
remote images in mail messages" box is unchecked in Tools->Options->Advanced,
the remote images are not displayed (all images end up drawing a box with a red
circle in them).
If I change the mail start page in Tools->Options->General to, for example,
http://www.google.com and go to the mail start page (Go->Mail start page) this
error message is displayed :
Proxy authorization required
Username authentication is required for using this proxy. Either your browser
does not perform proxy authorization, or your authorization has failed.
Of course, if the mail start page is an url which matches something in "No proxy
for" it works fine.

Reproducible: Always

Steps to Reproduce:
1. With a proxy which required username authentication
2. Configure Thunderbird in manual proxy configuration
3. Change the mail start page to http://www.google.com (bugzilla.mozilla.org if
you prefer)
4. Go to the mail start page

Actual Results:  
The proxy send an error message :
Proxy authorization required
Username authentication is required for using this proxy. Either your browser
does not perform proxy authorization, or your authorization has failed.


Expected Results:  
Thunderbird should have displayed the google main page.

A workaround does exist :

If you reply to a mail that contains external elements like images, Thunderbird
asks for the proxy authentication and all the content of the mail is displayed
in the "reply-to" window. After this, all the mails you will access to will be
displayed entirely.

Thanks for the workaround.

Here is another one: If you hold your nose and jump up and down twice, you will
get the same effect. (Kidding of course. :) )

Dear Friens I have Mozilla Thunderbird 0.5 (20040207) running on a Pc witn Win
XP Pro Ver. 2002 SP 1

-I have Thunderbird configured to connect manually with a proxy
(tools/options/advanced/connection/manual connection to proxy) but when I
display a message with remote images it don't display them, nor ask me for
user_name/password.

Reproducible: Always
Steps to Reproduce:
1. Open ThunderBird configured in order to use a proxy that needs a
user_name/password.
2. Select a message with remote images.

Actual Results:  
The remote images are not shown.

Expected Results:  
It must ask for proxy user_name/password and then display remote images.

-If I right click on image and select "view image" a caption only windows open
and does nothing else.

Workaround (quoted from this bug 221772):
- If you reply to a mail that contains external elements like images,
Thunderbird asks for the proxy authentication and all the content of the mail is
displayed in the "reply-to" window. After this, all the mails you will access to
will be displayed entirely.

Mozilla comparision:
- With Mozilla 1.6 this problem does not happen: if you had accessed to the
proxy Mozilla itself the remote images are shown. This does not happen in
Thunderbird.

In my opinion this is a bug that compromise any serious effort to struggle with
MS OUTLOOK within a LAN with proxy.

I hope that in any future ver of TB there will be a full support to proxy: this
is a RFE and I do not agree with SEVERITY NORMAL

There are an easy workaround in bug 232856, with other usefull information (HTML
code that causes the bug ...)

The reply-to workaround only works for that "session" of thunderbird. If you 
close down the app and start it again the problem returns. The same results can 
be achieved by doing a Print Preview. Can the same code that causes the promt 
when doing a print preview be implemented in the normal mail view by any 
chance. I don't know anything about programming so that could be a dumb 
question. If so, sorry.

This bug is in version 0.6 as well, on all Windows Versions I have access to. At
the moment our University is arguing about Outlook vs TB, and this bug is the
one which is loosing the battle for TB to be our new "preferred" mail client :-(

Better as a depends.

You have to test and verify in Thunderbird separately anyhow.
