Web UI not functioning in Firefox 18, working in IE

[flemlion13]

The Web UI is not working for me anymore.
I'm currently on qBittorrent 3.0.6 and Firefox 18.
The UI starts to render in Firefox, but the torrent pane stays empty, and none of the actions work.

When connecting with IE 9, the Web UI is fully functional.
