As a reminder, Firefox 3.0.1 has a known crash problem with a wide variety of windowless mode SWFs. This has already been fixed in the Mozilla code tree and alpha builds are available for download. However, if you would prefer to wait until a new official Firefox release, you may wish to disable windowless mode in the Flash Player. You can do this (on any platform) by setting WindowlessDisable=true in the mms.cfg (which lives in /etc/adobe on Unix platforms).
