Is there any way to do this? I'm trying to send a GET request to a website, but I want to customize my UserAgent. Is there any way to do this in pure HTML and JavaScript? I'd like it to all execute locally.

This is working for me.

Object.defineProperty(navigator, 'userAgent', {
    get: function () { return 'Mozilla/5.0 (Windows NT 6.2; WOW64; 
    rv:28.0) Gecko/20100101 Firefox/28.0)'; }
});

It is an updated version of code4coffee's answer as Object.prototype.__defineGetter__() is deprecated: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineGetter
