Stateful browser access is one of the harder problems in web automation, and most tools ignore it.

What it is: Preferred Browser lets Manus Browser Operator use a designated Chrome session as its default environment, so automation tasks inherit the sign-ins, extensions, and network access already set up in that browser.

The pattern Manus is enabling here is closer to how ops teams actually work: one dedicated machine, always online, signed in everywhere it needs to be. Preferred Browser formalises that pattern inside Manus. You set the browser once. You start tasks from wherever you are. Manus handles the routing.

What makes it different: The separation of "where I trigger the task" from "where the browser runs" is what makes this genuinely useful for recurring workflows. It's not about convenience -- it's about reliability across runs.

Key features:

Set one Chrome browser as the default for all Browser Operator tasks
Trigger tasks from any device logged into the same Manus account
Consistent environment across sign-ins, permissions, and extensions
Offline fallback to other authorized browsers
Part of existing Browser Operator and My Browser flows

Benefits:

Stable automation environment without per-device setup
Tasks requiring account state or specific extensions work without reconfiguration
Active workstation stays uninterrupted while automation runs elsewhere

Who it's for: Power users and small ops teams using Manus for recurring web tasks that require persistent account access or environment-specific configurations.

The feature is narrow. The problem it solves is not.
