Detect MS-Edge Extension Using JS

In this blog, we are going to learn How To Detect MS-Edge Extension Using JS.

Every Edge extension has a unique ID from which we will identify the extension.
Every Edge extension also has a manifest.json File.
The difference between chrome and MS-edge is all about the extension ID.

Step 1: – Get The ID of the extension, open the extension manager in the Edge browser, and open the detail page of that extension.

Step 2:- Create a Function in your js file Namely UrlExists().

function UrlExists(url, cb) {
  $.ajax({
   url: url,
   dataType: 'text',
   type: 'GET',
   complete: function (xhr) {
     if (typeof cb == 'function')
        cb.apply(this, [xhr.status]);
     }
  })
}

This function will return status 200 if the manifest.json file is found.

Step3:- Create a URL as per your Extension ID: chrome-extension://YOUR EXTENSION ID/manifest.json

Step4:- now call UrlExists() function by giving your URL

UrlExists('chrome-extension://YOUR EXTENSION ID/manifest.json', function (status) {
                if (status == 200) {
                    alert('Extension Detected')
                }
                else{
                   alert('Extension Not Found')
                }                                
            })

In the end, it will look like following

function UrlExists(url, cb) {
            $.ajax({
                url: url,
                dataType: 'text',
                type: 'GET',
                complete: function (xhr) {
                    if (typeof cb == 'function')
                        cb.apply(this, [xhr.status]);
                }
            })
        }
 UrlExists('chrome-extension://YOUR EXTENSION ID/manifest.json', function (status) {
                if (status == 200) {
                    alert('Extension Detected')
                }
                else{
                   alert('Extension Not Found')
                }                                
            })
