I've noticed it on occasion and not just here at WC... other sites (eg devart) don't render properly at times, either. I've also noticed that FF 3.0.6 is more resource intensive than earlier editions... CPU spikes over 20% - 30% and it appears there may be a memory leak. If FF is opened, particularly on 'flash' intensive pages, while *say* converting video or editing music, etc, my cursor gets all jittery and doesn't go where I want it to as I want it to. This does not occur when on the same pages in IE7, so I tend to think the poor rendering is a FF issue, particularly when other apps are running.
