Confirmed. This only happens on trunk builds, 1.5 is unaffected. In SeaMonkey I
get a dialog stating that a script is taking a long time to execute, so perhaps
the script is going into an infinite loop somewhere? Still, it's odd that the
loop didn't happen in earlier builds. I attempted to debug in Venkman but for
some reason the trunk build would only load part of the scripts, and not the
portion that I suspected contained the bug. 1.5 loaded the entire script, but of
course debugging there wasn't useful since it didn't exhibit the bug.

I created a test account with the site, username and password are moz_test.
