Possible to run userscript in IE11

I have a custom userscript that I'm running in Chrome and Firefox using Tampermonkey/Greasemonkey.

Is there any way of using this script in IE11? Or is there any plugins for IE11 that does what Tampermonkey/Greasemonkey does?



TrixIE WPF4.5 claims to emulate Greasemonkey on IE11.

Unfortunately, the original Trixie and IE7Pro stopped working around IE8-ish.


A simple Google Search (I searched "greasemonkey for IE") yields various alternatives available for other browsers:


For Internet Explorer, similar functionality is offered by IE7Pro,[19] Sleipnir,[20] and iMacros.


Fiddler supports modifying the response of http requests.
We can use this feature to load userscript in any browser, include IE8.

This is an example:

static function OnBeforeResponse(oSession: Session) {
    if (m_Hide304s && oSession.responseCode == 304) {
        oSession["ui-hide"] = "true";
    // match url
    if (oSession.fullUrl == "http://apply.ccopyright.com.cn/goadatadic/getR11List.do") {
        var script = System.IO.File.ReadAllText("C:\\GitHub\\@selpic\\P660_printer\\Printer\\scripts\\form-save-load.js")
        oSession.utilReplaceOnceInResponse("</body>", "<script>"+script+"</script></body>", true);

I use localStorage to make it work, which is supported by IE8 or later.


  1. Run the following code in IE's developer tool when the current window is in the domain where you want the script to run in:
var scriptName = 'Hello world';
function scriptBody(){
//---userscript starts--->

document.body.innerHTML = '<h1>Hello world!</h1>';

//---userscript ends--->
var script = scriptBody.toString()
  .split('//---userscript starts--->')[1]
  .split('//---userscript ends--->')[0];
localStorage.setItem(scriptName, script);
  1. Create a bookmark and modify the URL into:
javascript:(function(){eval(localStorage.getItem('Hello world'));})()


  • No additional plugin needed.
  • Almost no script text length limit.


  • Need a user to click on a bookmark to run the script.
  • Need a reinstall if a user clears the browser cache.

Just open Developer tools (press F12) and paste your script to Console, and then run it (Ctrl + Enter).
