Hi,

looks like the current wiki code has a problem with  FireFox 9.0, the menu is displayed under the main content div. It seems (http://support.mozilla.org/en-US/questions/906789#answer-290813 or http://forums.mozillazine.org/viewtopic.php?f=25&t=2392487) like a browser sniffing problem in wiki javascript code:

This is caused by browser sniffing that has been broken in Firefox 9. The property navigator.taintEnabled is no longer supported so the wrong css file gets loaded which sets the margin-left of the div column-content to zero. As a result there is less room for the navigation div which is pushed down.

Don't know whether FireFox devs will get back  the
navigator.taintEnabled property or the wiki code base should be patched... The same problem appears on a lot of  other wiki sites (including, for example, http://k5wiki.kerberos.org)
