679519 - Yahoo! Mail attachment upload doesn't send user and password to proxy

Status: UNCONFIRMED

(Firefox :: General, defect)

Description

[Ivan Baldo]

User Agent: Mozilla/5.0 (X11; U; Linux i686; es-AR; rv:1.9.1.16) Gecko/20110701 Iceweasel/3.5.16 (like Firefox/3.5.16)
Build ID: 20110701113851

Steps to reproduce:

1 - Configure a Proxy that asks for user and password (in my case Squid).
2 - Enter to yahoo.com webmail.
3 - Create a new email and try to add an attachment.


Actual results:

It waits indefinitely.
From my Squid access.log I see that it access *.attach.yahoo.com but without sending the proxy user and password so Squid correctly denies it.
Tried with Firefox 6.0 and had the same problem.


Expected results:

It should had sent the user and password to the proxy as it always does.

Attachment: Log entering Yahoo mail and waiting without success for the upload of an attachment.

Look for attach.mail.yahoo.com.
In the Squid access.log I get:
TCP_DENIED/407 2018 POST http://ne1.attach.mail.yahoo.com/us.f1218.mail.yahoo.com/ya/upload
_with_cred? - NONE/- text/html
That clearly shows that the user and password for the proxy isn't being sent by Firefox.
