221236 - hangs when voting in IMDB

Status: VERIFIED DUPLICATE of bug 220603

(Core :: Layout, defect)

Description

[Jonathan Baron]

When voting in IMDB, the page hangs.  This happens in all
recent versions of Mozilla, including 1.4, on Linux.  It
is a result of something new in IMDB.  But I should not
have to kill Mozilla to get it to stop.

I managed to look at the offending page, and it looks like it has an
error.  There are two <script> </script> sections.  The first one has
stuff about google_ad's.  The second one, right below it, ends with
</noscript> instead of </script>.  I still think that Mozilla should
not hang when this happens.  In other cases like this, it times out
and produces an error message.

Perhaps this bug belongs in "javascript" rather than "layout".
I don't know how to switch it.  In the meantime, I'm not going to
report the error to IMDB.  (And I'm not going to vote.  This happens
with all the voting pages.)

Probably caused by the same ad code as bug 220603

I was wrong.  There is a </script> at the end.  Sorry.
But the offending section is indeed this one:

<script type="text/javascript" language="JavaScript"
src="http://pagead2.googlesyndication.com/pagead/show_scraped_ads.js"></script>

If I use my downloaded version of the page, it still hangs when this is present.
But when I remove this, I do not get the hang.  (Of course I still can't vote.)

I'm going to try to load that page now, but I will complete this form first.
I might have send another message.

Two new findings:
1. Many other pages in IMDB show the same behavior (and surely
have the same ads).
2. You can get out of the "hang" by holding down alt-back-arrow
(back button) so that the key repeats continously.  Eventually
it works.  (But one should not have to do this.)
