Can't prevent some browsers events

[alexfrad]

Hi,
I've been trying to add this to a website for quite some times. Everything works fine on Chrome and Opera, but when comes the time for Firefox and Edge the browser actions happen before the ComboKey's one.
For example:

$(document).ready(function () {
    var cb = new Combokeys(document);
    cb.bind('option+t', function(e) { debugger; console.log('Hello World'); return false; });
}

When doing the action on Firefox the 'Tools Menu' appear and then I get to do on debugger, etc.
In Edge, firing alt+d select the browser navigation bar.
Some help would be nice!
Thanks, Alexandre.
