Firefox sometimes gets a bad reputation for crashing or locking up when a plugin such as Adobe Flash or Windows Media Player causes the problem. Add code to Firefox (or write an extension) so that when a plugin misbehaves, a dialog is presented informing the user so that they can take corrective action (disabling the plugin) or filing a bug with the right party (this warning could be similar to the warning that appears when a JS script in a web page hogs too much CPU time. As a minimum it should identify that a plugin is to blame; better would be to inform the user of the plugin's name; best would be to provide an option to temporarily disable the plugin).
