Browser Use ignores public-link routing preference and opens GitHub in Codex browser

What version of the Codex App are you using?

26.814.5517.0

What platform is your computer?

Windows 11 Business 10.0.26200, x64

What issue are you seeing?

Codex ignored the configured browser-routing preference when Browser Use tried to open GitHub.

The Codex settings are configured so that:

• Public links open in Google Chrome.
• Only local links open in the Codex in-app browser.

Despite that configuration, Browser Use selected the Codex in-app browser for this public GitHub URL:

https://github.com/settings/repositories

The resulting tab opened the GitHub sign-in page inside the Codex browser instead of opening the URL in Chrome.

What steps can reproduce the bug?

1. Configure Codex to open public links in Google Chrome.
2. Configure Codex to use the Codex browser only for local links.
3. Ask Browser Use to open a public GitHub URL, such as https://github.com/settings/repositories.
4. Observe that Browser Use opens the public GitHub URL in the Codex in-app browser.

What is the expected behavior?

Browser Use should honor the configured routing preference and open public GitHub URLs in Google Chrome. The Codex in-app browser should be selected only for local links.

Additional information

The problem was reproduced while Browser Use was trying to open GitHub during a check of the account-level default-branch setting.

Start by tracing the Browser Use link-opening path and the settings that distinguish public links from local links. Reproduce the case with https://github.com/settings/repositories using the reported Chrome and Codex browser preferences, then verify that public URLs open in Chrome while local URLs still use the in-app browser.
