2. Select the compressed file of the extension you need (currently, only ZIP format is supported).

Step 2: Create a Group

1. Create a new group.

2. Check the uploaded extension.

Step 3: Create a Profile

Create a profile within the current group.

After launching, you will see that the extension has been successfully loaded.

Step 4: Launch in Nstbrowser Docker

1. Pull the Nstbrowser Docker image and start the container:

docker pull docker.io/nstbrowser/browserless:latest

docker run -d -it \
  -e TOKEN=API_KEY \
  -p 8848:8848 \
  --name nstbrowserless \
  nstbrowser/browserless:latest

2. Connect to Nstbrowser Docker via Puppeteer and capture a screenshot of the extensions:

import puppeteer from "puppeteer-core";

async function execPuppeteer(browserWSEndpoint) {
  try {
    const browser = await puppeteer.connect({
      browserWSEndpoint: browserWSEndpoint,
      defaultViewport: null,
    });

    const page = await browser.newPage();

    await page.goto("chrome://extensions");

    await page.screenshot({ fullPage: true, path: "extensions.png" });

    await browser.close();
  } catch (err) {
    console.error(err);
  }
}

async function createAndConnectToBrowser() {
  const browserWSEndpoint = `ws://127.0.0.1:8848/devtool/launch/d924280c-f5d1-4017-9bba-947a35afe0dd`;
  await execPuppeteer(browserWSEndpoint);
}

createAndConnectToBrowser().then();
