What are the cases when return false does not do the same thing as e.preventDefault() ?

(Note I'm not talking about jQuery events.. but JavaScript events in general)

The only situation I can think of is a click event on a hyperlink (if you return false in the handler you will still be redirected to the website)

Note that if its not a click event but a mousedown event on the hyperlink return false works same as e.preventDefault().

I believe that return false is equivalent to e.preventDefault(); and e.stopPropagation(); at the same time. However, I recommend that you use the functions and the return false for future and past browser compatibility:

$("#something").click(function(e){
    alert("Something was clicked");
    e.preventDefault();
    return false;
});
