[Greasemonkey] Define showModalDialog with GM

[David Kaspar]

This is my first attempt at improving the usability of an IE-only site.

I would like to replace a showModalDialog function call (which does not
work in FireFox) with a simple call to confirm. Like so:

window.showModalDialog = function(a,b,c) {
    return window.confirm("Are you sure?");
}

No matter what I try (window., document., unsafeWindow. or just the
function name) I am not able to define the function.

The same JS error occurs: "window.showModalDialog is not a function".

The function is called from the page like this:

function someFunction() {
      ...
	  
	var confirmUn = window.showModalDialog("http:...",confirmUnread,
WinSettings);

	...
}

The function is defined in a nested frame, does this matter?

Thank you,

David Kaspar
