JavaScript alert not working in Firefox 6
I often execute Javascript code in the address bar (mostly for debugging and testing): javascript:alert(some_function_with_interesting_return_value('blah')); Or - more obvious: javascript:alert('interesting value');
This doesn't seem to work anymore with Firefox 6: Error: uncaught exception: ReferenceError: alert is not defined
How is it possible for alert() not to be defined ?
I've double-checked it with Firefox 5, Epiphany, Midori and Chromium - works fine.
