Firefox 9.0.1 Broke Internal Wiki Layout
问题 The most recent version of Firefox has messed up our internal wiki layout so that the left bar menus are displayed below the content on all pages now. I've tried using multiple resolutions and window sizes and the problem persists so that doesn't appear to be the issue. There are no problems with Chrome or IE however. A screenshot of the problem is attached here for you to see. 回答1: You're using an old MediaWiki version. It does UA sniffing and sends different code to different browsers,
