The browser extension

Apps & integrations · Last updated 16 July 2026

Some of the work happens while you are actually looking at the website. The TLDTrack browser extension puts a side panel next to any page you are browsing, so you can see that page's notes and its compliance and accessibility issues, highlight the exact element in question, and set up a monitor, all without switching tabs back to the dashboard.

What it is

A Chrome extension (Manifest V3) that opens as a side panel beside the current tab. You connect it to your TLDTrack account once; after that it recognises when you are on a site you monitor and shows that page's notes, tasks, and open compliance and accessibility findings, and lets you add a monitor for an element on the page.

The extension is owned-only: it resolves the site you are viewing to a domain in your account by its hostname, and shows nothing for a site you do not monitor. It talks to a small API (/api/ext/*) using a bearer token that lives in the extension's background worker and never reaches the page itself.

Why it matters

Reviewing a site is far quicker when the findings sit next to the page instead of in another tab. You can read an issue, click to highlight the element it refers to on the live page, and jot a note in context.

It is built for the moment of review. Rather than context-switching between the browser and the dashboard, an agency reviewer or site owner can work down a page's issues in place, capture element-level monitors by pointing at the thing on screen, and leave notes exactly where they belong.

How to install it

The extension is published on the Chrome Web Store, so it installs like any other Chrome extension:

  1. 1
    Open the TLDTrack extension on the Chrome Web Store, or use the link on our browser extension page.
  2. 2
    Click Add to Chrome and confirm.
  3. 3
    Click the TLDTrack toolbar icon to open the side panel. It will show a "Connect to TLDTrack" button until you complete the connect step below.

Chrome and other Chromium browsers

The store version works in Chrome and in Chromium browsers such as Edge and Brave.

Connecting it to your account

The extension holds a bearer token that identifies you and your organisation. You issue that token from inside your TLDTrack account, so no password ever passes through the extension:

  • From the side panel, choose Connect to TLDTrack. The extension opens an Authorise page in your logged-in dashboard, passing along its own Chrome extension id.
  • On that page you approve the connection. TLDTrack mints a token (it starts with tkx_) and hands it straight back to the extension. The token is stored in the extension's background service worker and is only ever sent to www.tldtrack.com.
  • Each token is valid for 90 days and is tied to your user and organisation. You can see and revoke connected browsers from your account settings at any time, and you can disconnect the current browser from the side panel itself.

Treat the token like a password

A connection token gives access to your monitored sites' notes, findings and monitors. If you stop using a browser, or a machine is no longer yours, revoke that connection from your settings. Revoking it logs that browser out immediately; nothing else is affected.

What you can do in the side panel

When you are on a page that belongs to a site you monitor, the panel comes to life. The main things it offers:

  • Site recognition. It resolves the current page's host to one of your domains and tells you whether the site is tracked and monitored.
  • Notes and tasks for the page. Read the notes and tasks attached to that exact URL path, add a new note or task, tick one off, or delete it. These are the same per-page notes and tasks you see in the dashboard's page workspace.
  • Compliance and accessibility findings. See the open compliance and accessibility issues that TLDTrack has recorded for that page, and highlight the element each one points to directly on the live page.
  • Element monitors. List the visual monitors already watching that page, and create a new selector-native monitor by pointing at an element, so you can watch a specific price, banner or block of text for changes. You can also remove a monitor you no longer need.

What you need

  • A TLDTrack account with sites you monitor. The extension only ever shows data for domains already in your account; it never exposes a site you do not own.
  • The compliance and accessibility checks running if you want their findings in the panel. Set those up first from the site's monitoring tabs. See compliance checks and accessibility.
  • Chrome (or a Chromium-based browser that supports MV3 side panels), since the extension is built to the Chrome extension platform.

Where to set this up

Good to know

  • The extension is owned-only: it works with notes, findings and monitors for your own sites and cannot see anything for a site you do not track.
  • Your connection token stays in the extension's background worker and is only sent to TLDTrack; the page you are viewing never sees it.
  • It installs from the Chrome Web Store, and Chrome keeps it up to date.
