What is Manus Browser Operator?

Manus Browser Operator is a browser extension that enables Manus to operate directly within your local browser environment. Unlike the cloud browser that Manus typically uses, Browser Operator works with your actual browser—complete with your existing logins, sessions, and local IP address. This transforms your browser from a passive viewing tool into an active workspace where Manus can execute complex tasks using the premium tools and authenticated systems you already access.

​

Why Local Browser Matters

​

The Authentication Advantage

When Manus works in your local browser, it operates with your trusted credentials and local IP address. This means: No Login Barriers: The system recognizes activity as coming from your trusted machine, eliminating unfamiliar login attempts, CAPTCHA interruptions, and session expiration issues. Reliable Access: Because the activity appears legitimate to websites, it clears standard access barriers automatically and maintains active sessions. Premium Tool Access: Manus can work with subscription services you’re already logged into—Crunchbase, PitchBook, SimilarWeb, Financial Times, Semrush, Ahrefs, or any authenticated platform.

​

Cloud Browser vs. Local Browser

Cloud Browser (Default):

• Sandboxed, isolated environment
• Works across any device without installation
• Ideal for most research, analysis, and content creation tasks
• No local setup required

Local Browser (Browser Operator):

• Uses your actual browser with existing sessions
• Access to authenticated systems and premium tools
• Trusted local IP and credentials
• Best for workflows requiring logged-in access

Both work together seamlessly—Manus automatically uses the appropriate environment for each task.

How It Works

​

3-Step Process

Step 1: Activate “My Browser” Connector Navigate to Connectors and toggle on “My Browser.” This tells Manus to use your local browser for tasks requiring web access. Step 2: Authorize the Session When you assign a task, Manus requests permission to take control. Click “Authorize” to grant one-time access. You remain in command of when and how Manus interacts with your browser. Step 3: Monitor in Dedicated Tab Manus opens a new tab within a tab group named after your current task. You can:

• Watch the task unfold in real-time
• Take over by clicking into the tab
• Stop instantly by closing the tab
