The mousedown and click events occur together and are not sharing the same event object.

Calling e.preventDefault(); in the mousedown event is not able to prevent the default click behaviour on the click event.

Why it works for you in Chrome is most likely a different reason or a even false positive.

To Demonstrate, assuming you have the following HTML:

HTML

<a href="http://jsfiddle.net/" id="whichkey">link to google</a>
<div id="log"></div>

The following Script will not prevent the default behaviour and clicking the link will always work:

JavaScript

$("#whichkey").on("mousedown", function (event) {
    $("#log").html(event.type + ": " + event.which);
    event.preventDefault(); // won't work!
    //return false; // won't work either!
});

However, if you add the following script to the above, then it will work.
