How to disable Javascript when using Selenium?

I am wondering how do I disable javascript when using selenium so I can test server side validation.

I found this article but I don\'t know what to really do. Like I

Answer 1

I was trying to solve this problem and found this blog but the first post has a link that is no longer valid. But I finally found the code to place inside the user-extensions.js that works. Here it is:

Selenium.prototype.doDisableJavascript = function() {
    setJavascriptPref(false);
};

Selenium.prototype.doEnableJavascript = function() {
    setJavascriptPref(true);
};

function setJavascriptPref(bool) {
   prefs = Components.classes["@mozilla.org/preferences-service;1"]
           .getService(Components.interfaces.nsIPrefBranch);
   prefs.setBoolPref("javascript.enabled", bool);
}

Hope this save the time it took me to find it.
