Get a list of installed extensions with javascript

Question

Im trying to figure out if it is possible to get a list of all installed browser extensions using javascript

I understand it is possible on

chrom using - chrome.extension reference firefox - using Application.extensions.all

But is it possible on IE and Safari ?

Unless the browser has provided a specific API to access this, no. Where are you running this JavaScript? — Qantas 94 Heavy, Nov 07 '13 at 08:20
well is there a specific API for that on chrome/firefox and ie ? — lior r, Nov 07 '13 at 12:23
What is this for though? Is this a webpage, is this an extension itself, userscript, what? — Qantas 94 Heavy, Nov 07 '13 at 12:30
it is a webpage that suppose to list the current installed extensions — lior r, Nov 07 '13 at 12:40

You can only do that from the Chrome Context (Firefox) or Background Script (Chrome). It is not possible to get the list of extensions from a webpage.

It's not possible to get a list of all the installed extension with "Chrome tabs". enter image description here you only able to get extension list view extension tabs.

Follow these steps:

Note: These steps are compatible with manifest V3 and V2

Add managment permission to manifest file

...
"permissions": [
   "management"
]
...

Call to get all installed extensions list in the background.js file

chrome.runtime.onMessage.addListener(function (request, sender, sendResponse) {
    const result = detectMessageType(request, sender);

    // Check if result exists
    if (result) {
        result.then(response => {
            return sendResponse(response);
        });
    }
});

function detectMessageType(request, sender) {

    // Check background request type
    if (request && request.type) {
        switch (request.type) {
            case 'get_all_installed_extensions': {
                return getAllInstalledExt(request.options, sender);
            }
        }
    }
}

async function getAllInstalledExt() {
    const gettingAll = chrome.management.getAll();
    return await gettingAll.then(infoArray => {
        return infoArray.filter(item => item.type === "extension").map(item => item.name);
    });
}

Then in your main js file of your extension app, write this to get the list of installed extensions

chrome.runtime.sendMessage({type: 'get_all_installed_extensions'}, response => {
    console.log(response); // print the list of installed extensions
});
