The problem originates from Firefox's 'firefoxurl://' URI handler (a Slashdot reader provided an example: when invoking Cmd.exe, Firefox will display a dialog box warning that it is about to call an external program).
The release of Firefox 3 beta will be delayed by six weeks, with the current scheduled date set for September 18th. Some speculate that the final official version may not be released until 2008."
