119686 - "Alert before downloading an image" hangs at rcm-images.amazon.com

Status: VERIFIED DUPLICATE of bug 107806

(SeaMonkey :: General, defect)

Description

[Frankie]

At least one other person is experiencing this, so I'm not crazy. In MacOS X
10.1.2 with Mozilla 0.9.7 {2001122106}, with Preferences / Privacy / Images set
to "Alert me before downloading an image", attempting to load a page that
includes a javascripted ad banner from rcm-images.amazon.com will cause the
dialog box to hang. Mozilla stops accepting input from either mouse clicks or
keyboard. The user must switch to a different application and use Force Quit.

One example of the offending code is:
http://rcm.amazon.com/e/cm?t=mtgnewscom&l=rc1&p=1&o=1 (within the page
www.mtgnews.com)

Worksform for me os x same version CFM build 2002010808.
Reporter can you test with a newer build ?

Yes, http://www.mtgnews.com causes Mozilla nightly 2002011108 to hang at the
rcm-images.amazon.com image warning dialog box.

mtgnews.com uses some rather funky CSS positioning for this particular advert.
If I get a chance I will try to reduce the test case.

2002012403 still freezes. Sorry I haven't reduced a testcase.

With various other tabs open, I dragged a link for
http://www.mentalengineering.com onto an existing tab. The usual "The site
www.mentalengieering.com would like to load an image" dialog box pops up, then
a split second later an identical dialog pops over top of it.

It clicked "Yes (remember)" for the both dialogs, then Mozilla crashed.

Found another site with the identical freeze ("rcm-images.amazon.com wants to
load an image") -- http://www.asktog.com

Although Tog's HTML is surprisingly non-compliant, it's clean enough that I can
use it to create a test case. I'll post it in a few minutes.

Attachment: testcase for image dialog freeze

Okay, I have built a gorgeous testcase, and if the following details aren't
enough to solve the problem, then there's something REALLY wrong:

1) if you load moz-breaker.html from a remote web server then it DOES set off
the image warning dialog box, and Mozilla FREEZES right there. Feel free to hit
my copy at http://jhunix.hcf.jhu.edu/~fuy/moz-breaker.html

2) if you load moz-breaker.html locally using file:/// then it does NOT set off
the image warning dialog box, and the page works. The remote images LOAD
automatically, which strikes me as a security failure.

3) if you load moz-breaker.html from http://localhost (using OS X Apache) then
it DOES set off the image warning dialog box, and the page WORKS. Your image
loading preferences are honored (and added to the Image Permissions list if you
checked the Remember box).

So when can I see this move from Unconfirmed to Assigned to Fixed?  :-)
