Reproducible: Always
Reporter, can you attach a reduced testcase to show your problem? (Click on
"Create a New Attachment" and go from there).

Also, have you tried a nightly (1.1beta) build?

Reporter can you please shorten that to a simple html attachment with only the
parts which exhibit this problem (start trimming out code/html until you have
only the REQUIRED parts to show this bug)

Thank You.

testcase

I attached the file "after.html".
Everything seems to work normal.
Definitly no crash

it's not about a crash of Firefox, it's about reproter's script not working as
expected. Reporter, bugzilla is not the right place to ask for web developer
support, please use other places for that. Regarding your example, it's not
clear whether it's a mozilla bug or your bad code. If you're able to create a
minimized testcase showing a bug in mozilla, please create it and attach it
here. Thanks.

There is no <MARQUEE> tag in HTML. The poster might have a look at the
moz-behaviors.xml at http://dean.edwards.name/my/ , which I think is designed to
do what he wants.
This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
Thank you for your help in this matter.
