Manus introduces Preferred Browser, enabling users to integrate a custom browser for seamless automation with pre-configured sign-ins, extensions, and network access.

Manus has unveiled a new feature called Preferred Browser, enhancing its Browser Operator tool by enabling users to designate a custom Chrome browser for web automation tasks. This update, announced on May 12, 2026, aims to streamline workflows by ensuring consistent access to pre-configured browser environments.

The Preferred Browser feature allows users to specify one authorized Chrome browser containing the necessary sign-ins, extensions, and network permissions for automation. This eliminates the need to repeatedly configure browser setups across multiple devices, significantly reducing inefficiencies in web-based tasks.

How It Works

Users can set up a dedicated Chrome browser on any device, such as a primary workstation or an underused computer like a Mac mini, and authorize it as the preferred environment. Once configured, Manus will utilize this browser for tasks such as accessing analytics dashboards, internal tools, or vendor portals. Key to the feature is its ability to maintain continuity in workflows by keeping the browser session signed in with pre-installed extensions and permissions.

Critically, users can initiate tasks from one device while Manus operates through the preferred browser on another. For instance, a laptop user can launch a task that Manus executes using a pre-authorized desktop browser, effectively separating automation activity from the user’s active device.

Key Capabilities

• Custom Browser Integration: Designate a Chrome browser with the required setup as the default for automation.
• Seamless Cross-Device Functionality: Start tasks from one device and execute them via the preferred browser on another.
• Preserve Workflow Configurations: Maintain sign-ins, extensions, and permissions in a single, reliable browser environment.
• Fallback Mechanism: If the preferred browser is offline, Manus can switch to another authorized browser for task execution.

Why It Matters

This update addresses a recurring pain point for users who rely on browser-based automation. Previously, variations in browser setups across devices could slow down workflows or require repetitive configurations. With Preferred Browser, teams can centralize their browser environment, ensuring that Manus starts each task with the correct setup, saving both time and effort.

By decoupling browser activity from the primary work device, the feature also helps users avoid interruptions. For organizations leveraging dedicated devices for automation tasks, this offers an efficient way to repurpose underutilized machines.

How to Get Started

To enable Preferred Browser, users must:

1. Install the Manus Browser Operator Chrome plugin on the designated computer.
2. Log in to Manus and authorize the browser.
3. Test a simple Browser Operator task to confirm functionality.
4. Set the browser as the preferred device in the My Browser settings.
5. Ensure the computer and Chrome session remain online for uninterrupted operation.

Availability

Preferred Browser is rolling out as an update to Manus Browser Operator. While availability may vary by account, it represents a substantial improvement for users seeking a more efficient approach to browser-based automation.

For teams managing complex web tasks or recurring checks, this feature could prove invaluable, offering a practical solution to streamline and optimize their Manus workflows.
