Wikimedia Bugzilla is closed!

This is due to the following lines in your MediaWiki:Monobook.css:

/* Solution for ordered and unordered lists in firefox having float:left on its left side */
html>body DIV#bodyContent ol, html>body DIV#bodyContent ul {
display:table;
/*border:1px solid transparent;*/
}

Removing them makes the references show in multiple columns.

I'm sorry.doesn't work yet:

There is also

.ns-0 * #content ol{ /* for numbered lists */
display: table;
}

which only applies to the main namespace (that's why I didn't see it last time).
