Next code logs the fired events on window object (FIDDLE): If I right click on the body element for example, I'll get next log on console: for Firefox 54.0.1 1. ------- CLIC

It happens on my firefox too.

It's a registered bug, see https://bugzilla.mozilla.org/show_bug.cgi?id=184051

You can go around it by checking e.button value in the click handler.

window.addEventListener('click', function(e) {
    //when e.button==2, it's a right click, when 0, it's a left clicklogEvent('CLICK.' + e.button, e);
    if(e.button===2){
        //do context menu stuff
    }
})
