Thread:Project:Support desk/Issue with new Firefox 9.0.1 / Left Navigation box display UNDER content

My site: http://www.princevault.com

MediaWiki 	1.14.0 PHP 	5.2.13 (apache2handler) MySQL 	5.0.77

I was reported a bug with FF9 this morning, that appears to be linked to FF9.0.1 upgrade. The navigation boxes on the left doesn't show properly anymore, but under the main content. I have tested successfully all the other browsers (IE, Safari, Chrome, Opera), only FF9 display the boxes unproperly in Windows 7 as well as in Snow Leopard.

FF8 works well.

I've quickly checked the css in search of a way to correct that, unsuccessfully so far. If someone met a similar issue and patched it correctly, either in css or php files, please let me know.

I thank you in advance for your help. Regards.
