Status: UNCONFIRMED

(Core :: Widget: Cocoa, defect)

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:39.0) Gecko/20100101 Firefox/39.0
Build ID: 20150630154324

Steps to reproduce:

Cmd-Shift-/ by default opens Help menu search on Mac.

I was able to suppress the above shortcut for Chrome & Safari using below Javascript event handling.

But Firefox(Version 39 or older) is not honoring event suppression.
Below is the method.

if (event.keyCode == 66 && event.shiftKey && event.metaKey) {
    // Do something here
    event.preventDefault();
    event.stopImmediatePropagation();
}


Actual results:

It still shows Help menu search popup


Expected results:

Should suppress help menu search and honor the statements at //Do something here

if (event.keyCode == 66 && event.shiftKey && event.metaKey) {
    // Do something here
    event.preventDefault();
    event.stopImmediatePropagation();
}
