What the OpenClaw browser extension does
The OpenClaw Chrome extension is the bridge between OpenClaw’s browser tool and eligible tabs in a signed-in Chrome profile. It allows browser automation through Chrome’s chrome.debugger interface, so OpenClaw can work with tabs that already contain your cookies, accounts, and active sessions.

The extension popup is deliberately small. It reports the connection state, shows the current tab-access mode, and provides a Pause/Allow control for the current eligible tab. It is not a chat box, page-sharing panel, or tab copilot. You issue browser actions through OpenClaw; the popup controls whether the extension is connected and which tabs it can expose.
That distinction matters when diagnosing setup. Native-host registration, Chrome’s permission decision, profile selection, Gateway availability, and tab access are separate pieces. A green-looking installation report can coexist with a disconnected extension or a profile mismatch.

Requirements and supported arrangements
Prepare the machine that will actually host the Chrome session before installing anything. OpenClaw must be installed on that same machine, or an OpenClaw browser node must run there to provide the browser connection.
- Browser: use Google Chrome, Chrome for Testing, or Chromium.
- Operating systems: the guide documents macOS and Linux, and provides a self-contained native bootstrap executable for Windows.
- Gateway: a local setup needs
openclaw gateway runor the managed Gateway service running when the extension pairs. A browser-node setup uses the Gateway configured for that node. - Profile: the Chrome profile must be the one you intend to automate. A different Chrome profile can have different cookies, extensions, and open tabs.
On macOS, if you plan to use a browser other than Google Chrome, launch it once before setup so its user-data directory exists. Without that first launch, the installer may not find a usable profile directory.
There are two network layouts:
- Local: Chrome, the native helper, OpenClaw, and the Gateway are on one machine.
- Browser node: Chrome and the extension run on a separate host. The extension connects to the Gateway configured for that browser node, so commands must be sent to that node rather than to an unrelated local browser.
Install the extension through the normal path
The standard installer registers the native host and prepares the browser extension. Chrome still controls the final approval, so plan to complete the browser steps while the installer remains available.
- Run the installer on the Chrome host. Open a terminal and run
openclaw browser extension install. - Keep the command running. Leave the installer process available while you finish Chrome setup. Closing it before setup is complete can leave the native host registered but the pairing unfinished.
- Complete the macOS handoff when applicable. On macOS, the command registers the native host and requests the official Store extension. If Chrome was already open, fully quit and reopen it when convenient so Chrome loads the newly registered native messaging host cleanly.
- Approve or enable OpenClaw in Chrome. Chrome owns this permission decision. OpenClaw cannot restart Chrome or silently approve the permission for you.
- Finish the platform-specific extension step. On Linux and other supported Chromium browsers, add OpenClaw from the Chrome Web Store after native-host registration succeeds. On Windows, use the packaged
OpenClaw.BrowserBootstrap.exenative executable supplied by the installation. - Open the extension popup. Select the OpenClaw extension from Chrome’s toolbar or extensions menu and inspect its state before attempting automation.
Installation status and connection status are different signals. The installer can report that files, IDs, and native-host registration are correct even when the Gateway is stopped, the wrong profile is open, or the extension has not completed pairing.
What the installation report can and cannot prove
For automation or diagnostics, use the installer’s JSON output mode and examine each part of the report separately. The useful checks include:
- whether the extension was installed;
- whether Store discovery or approval is still pending;
- the unpacked extension ID and path, when using a developer install;
- whether the native host is present and healthy.
A successful report for those items does not prove that an extension instance is currently connected to the intended Gateway. Perform the live verification steps later in this guide.

An unpacked installation is useful when you need to inspect a local build, test a change, or avoid Store delivery during troubleshooting. It still requires the native host and a live installer session.
- Run
openclaw browser extension install --no-store. - Keep that command running while you complete the Chrome steps.
- Open
chrome://extensionsin the Chrome profile you intend to automate. - Turn on Developer mode.
- Select Load unpacked.
- Choose the path printed by the installer.
- Confirm that Chrome shows the OpenClaw extension and that its recorded unpacked path and deterministic extension ID match the installer’s output.
Do not substitute an arbitrary directory. The installer checks the recorded unpacked path and deterministic ID; loading a copied folder can produce a different ID or leave the native host pointing at a location Chrome is not using.
Configure OpenClaw to use the extension-backed profile
OpenClaw needs to know that browser actions should go through the extension connection rather than an isolated managed browser.

- Screen Size: 11.6"
- Select the built-in
chromebrowser profile in the command or integration you are using. - To make it the default, run
openclaw config set browser.defaultProfile chrome. - The equivalent profile definition uses
driver: 'extension'. - Start
openclaw gateway run, or ensure the managed Gateway service is running, before creating a fresh local pairing.
For a browser-node arrangement, configure the extension on the browser-node host and connect it to that node’s remote Gateway. The local machine running your OpenClaw command is not automatically the browser host. A command aimed at the wrong Gateway can return no tabs even though Chrome and the extension are healthy elsewhere.

Profile selection checklist
- Chrome is open under the profile containing the signed-in account and target tabs.
- The OpenClaw extension is enabled in that same profile.
- The configured profile name is
chrome, or your explicitly chosen profile points to the extension driver. - The Gateway or browser node is running and reachable from the host where Chrome is open.
- Any remote Gateway settings, profile names, ports, and authentication policy match on both sides.
Choose how much tab access to grant
The extension popup shows both connection state and the current access mode. Use that popup to decide whether OpenClaw should see every eligible ordinary tab or only the tabs you explicitly allow.
All tabs
All tabs exposes every eligible ordinary tab in the selected Chrome profile, except tabs you have paused for the current browser session. It is the mode used by fresh automatic pairings. This is convenient for workflows that move between several already-open pages, but it also gives the automation a broader view of the signed-in profile.
Pause and Allow
Use Pause or Allow for the current eligible tab when you need a quick per-tab boundary. Pausing a tab removes it from the extension’s usable set for the current browser session; allowing it makes that eligible tab available again under the selected access policy.
Narrower access modes
Select a narrower mode when broad exposure is unnecessary. This is the better fit for a single-page task, a profile containing sensitive tabs, or an attended session in which you want to approve access one tab at a time.
Access mode is part of the pairing state. Existing valid pairings keep their stored mode, while fresh automatic pairings use All tabs. If a pairing appears to have reverted to a different scope, inspect whether Chrome is reusing an existing valid pairing rather than creating a new one.
Verify a live connection before automating
Use two checks: the extension popup and the browser CLI. Neither should be skipped when a setup has just changed.
- Open the OpenClaw extension popup and confirm that it reports a connected state, not merely that the extension is installed or enabled.
- From a terminal, run
openclaw browser --browser-profile chrome tabs. - Run the command against the intended Gateway or browser node. Confirm that the listed tabs belong to the Chrome profile you opened and that the expected title or URL appears.
- If the list is empty, compare the active Chrome profile, the selected access mode, and the Gateway target before changing the extension installation.
The tabs command is a live discovery check. It demonstrates that OpenClaw can reach the extension connection and enumerate eligible tabs; an installation screen alone cannot demonstrate that.

| The installer reports success, but the popup is not connected. | Live pairing or Gateway | Refresh setup status, open the popup, confirm the Gateway or browser node is running, and repeat the live tab check. |
| Chrome shows the extension, but no tabs are listed. | Profile, access mode, or wrong host | Confirm Chrome is using the intended profile, check whether the current tab is paused, and run openclaw browser --browser-profile chrome tabs against the correct Gateway or node. |
| The extension cannot find its native helper. | Native-host registration | Run the installer again on the machine hosting Chrome, keep it running through setup, and inspect native-host health separately from Store approval. |
| The Store extension is present but disabled or awaiting approval. | Chrome permission | Enable or approve it in Chrome. OpenClaw cannot grant Chrome’s permission or restart the browser on your behalf. |
| An unpacked build loads, but pairing fails. | Path or deterministic ID | Repeat the --no-store installation, load the exact path printed by the installer, and compare the path and extension ID recorded by the installer with the entry in chrome://extensions. |
| A browser node works locally but not from the controlling machine. | Remote Gateway target | Point the command at the configured browser-node Gateway and verify its profile, port, and authentication policy rather than the local Gateway. |
| Connection broke after an upgrade or configuration change. | Mixed builds or mismatched settings | Check Gateway and browser-node versions, profile names, ports, and authentication keys or policy. The official documentation treats mixed builds and mismatched profile, port, or key settings as unsupported. |
Why restarting Chrome can help
Chrome loads native messaging registration and extension state during its startup lifecycle. On macOS especially, fully quitting and reopening Chrome after the installer registers the host can clear a stale browser process. Restarting is not a substitute for approval, profile selection, or a running Gateway, but it removes a common stale-process variable.
When to reinstall
Reinstall only after identifying which layer failed. Re-running the installer is appropriate when the native helper is missing, the unpacked path is wrong, or the extension ID no longer matches. It is not the first response to an empty tab list caused by a paused tab, a different Chrome profile, or a browser-node command sent to the wrong Gateway.

OpenClaw offers three practical browser choices. The extension-backed chrome profile is not interchangeable with the managed openclaw profile or the attended user flow.
| Mode | Browser context | Remote-debugging approval | Extension required | Access and host behavior | Best fit |
|---|---|---|---|---|---|
chrome |
Your real Chrome profile, including existing signed-in sessions | No blocking Chrome remote-debugging prompt through the extension path | Yes | Use the popup’s access mode and Pause/Allow controls. Chrome can be local or hosted on a separate browser node. | Remote automation that must use accounts and sessions already open in Chrome. |
openclaw |
Isolated, managed browser profile | Not applicable to the extension flow | No | Separate from the user’s everyday Chrome tabs and sign-ins. | Automation that should not touch a personal or work Chrome session. |
user |
A user’s browser through the DevTools attach flow | Someone must be present to approve Chrome’s remote-debugging prompt | No extension required | Attended attachment rather than extension-managed tab access. | Interactive sessions where a person is available to approve the prompt. |
Choose chrome when preserving an existing signed-in session is the priority and no one should have to sit at the machine to approve a remote-debugging prompt. Choose openclaw when isolation is more important than reusing cookies. Choose user when a person is present and an attended DevTools attach is acceptable.
Operate the extension safely in a signed-in profile
A signed-in profile contains more context than the page you intend to automate. Treat the extension’s access mode as an operational boundary, not merely a setup preference.
- Use a narrower access mode for one-off tasks instead of leaving All tabs enabled by default in a profile with unrelated work.
- Pause tabs that should remain outside the current browser session’s automation scope.
- Before issuing an action, check the popup’s current state and confirm that the intended tab is eligible.
- For unattended work, prefer a dedicated Chrome profile or a browser node whose open tabs are limited to the task.
- When isolation is required, use the managed
openclawprofile instead of exposing a personal signed-in session.
These controls do not change what Chrome accounts can access. They determine which eligible tabs the OpenClaw browser tool can see through the extension connection.

Platform-specific notes
macOS
- Run the installer on the Mac that owns the Chrome profile.
- If using a non-Chrome browser, launch it once first so its user-data directory exists.
- After native-host registration, fully quit and reopen Chrome if it was already running.
- Approve the extension in Chrome; the installer cannot make that decision.
Linux and other supported Chromium browsers
- Complete native-host registration first.
- Add OpenClaw from the Chrome Web Store in the Chromium browser you will automate.
- Make sure the browser profile and Gateway target match the host where the extension is installed.
Windows
- Use the packaged
OpenClaw.BrowserBootstrap.exenative executable. - Finish the browser approval and profile-selection steps in Chrome.
- Verify the live connection with the popup and the CLI rather than relying on the bootstrap installation result.
A repeatable setup checklist
- Identify the machine that will host Chrome, or identify the browser node that will.
- Open the intended Chrome profile and note whether the required signed-in session is present.
- Run
openclaw browser extension installon that host. - Keep the installer available while Chrome approval and enabling are completed.
- Use
--no-storeandLoad unpackedonly when you intentionally need a developer or diagnostic installation. - Set
browser.defaultProfiletochrome, or select that profile explicitly. - Ensure
openclaw gateway runor the managed Gateway service is running; for a browser node, use its configured remote Gateway. - Choose All tabs or a narrower mode, then pause tabs that should remain outside the session.
- Confirm the popup says connected.
- Run
openclaw browser --browser-profile chrome tabsagainst the intended Gateway or browser node and verify the expected tabs.
If the final check fails, return to the boundary that failed—Chrome approval, native host, profile, access mode, Gateway, or browser-node configuration—instead of reinstalling everything at once.
Bottom line
The OpenClaw extension is a connection layer for automating eligible tabs in a real signed-in Chrome profile. Install the native host, complete Chrome’s own approval, configure the chrome profile, keep the correct Gateway or browser node running, and set tab access deliberately. Confirm both the popup’s connected state and the CLI’s tab list; “Installed” alone is not proof that OpenClaw can control the browser.
