I have used this vbscript code:
this only works in IE, In FF and Chrome, it doesn’t work.
I also want to change the title of popup like in IE ‘Windows Internet Explorer’ is shown, I want to show here my own application name.
Unfortunately, there is no cross-browser support for opening a confirmation dialog that is not the default OK/Cancel pair. The solution you provided uses VBScript, which is only available in IE.
