安装了Flash CS3后,和firefox 兼容问题
解决方案
You need to go in to the Firefox config settings (type about:config in to the location bar) and search for dom.ipc.plugins.enabled.npswf32.dll double click that to set it to false. You may also need to set dom.ipc.plugins.timeoutSecs to -1. Now restart your browser and you should once again be able to debug your apps and dismiss the warnings as you used to do in the good old days. Ahhhhh bliss.
