Confirmed on 
http://hg.mozilla.org/mozilla-central/rev/6e4fb61ef475
Mozilla/5.0 (X11; Linux i686; rv:6.0a1) Gecko/20110516 Firefox/6.0a1 ID:20110516030622

At least it happens since Firefox3.0.x. on Linux.

It works to select sub-menus by mouse if I disabled JavaScript from Preferences

Comment 4

[Christian Pernot]

If you disable javascript after the page has loaded, it does not work.

FWIK, the javascript is used to adjust css properties on start (sub-menu up or down)

a friend of mine could reproduce the problem on vista, but not on seven.

I hope it will help.

It seems it works now, on firefox 12.
On the given URL, the behaviour is correct
