Install the CrabCode browser extension

This page installs the extension backend for browser automation. Regular automation defaults to the built-in browser mode (crabcode-browser); use this extension mode when you need real Chrome login state, OAuth/SSO, or intranet pages.

01

Download and unzip the package

Download crabcode-browser-extension.zip, unzip it, and keep the browser-extension/ folder. Chrome keeps reading the unpacked extension from this folder, so keep it in a stable location.

02

Load the unpacked extension in Chrome

Open chrome://extensions, turn on Developer mode, click Load unpacked, then select the unzipped browser-extension/ folder.

03

Verify the pinned extension id

The Chrome extension card must show imklgjagepjkegkcneifnholbpajhfji. A different id means an old or unofficial package is loaded; remove it and reinstall the package from this page.

04

Restart CrabCode and reconnect

Restart CrabCode and reconnect from Browser Automation. The official package manifest key and native-host allowed_origins are pinned to the id above, so no environment override is required.
