Chrome 136+ cannot be driven over CDP with the default user-data-dir profile

Export

Shows how to fix chrome 136+ cannot be driven over CDP with the default user-data-dir profile. Use it when you hit this exact problem. Skip it when your error message or symptom looks different.

TL;DR

If browser-use cannot attach to your real Chrome profile on Chrome 136+, copy your Default profile folder into a different directory and pass that new path as the user data dir in the browser config.

Steps

  1. If browser-use cannot attach to your real Chrome profile on Chrome 136+, copy your Default profile folder into a different directory and pass that new path as the user data dir in the browser config. Do not point it at the live default profile - Chrome refuses the CDP connection when another instance owns it. Close all existing Chrome instances before starting in debug mode, and use plain Chromium if you do not need the saved profile (cookies, logins, cache).

Expected: A maintainer confirmed the team is working on profile support and gave the interim workaround.

When to use

You are seeing this: Do not point it at the live default profile - Chrome refuses the CDP connection when another instance owns it. Use this skill when you run into "Chrome 136+ cannot be driven over CDP with the default user-data-dir profile".

When not to use
