YOUR FIRST BROWSER TASK

Nice work. You’re ready to put your browser to use.

You’re all set once your agent finishes authorization with the same Browser f6n account and confirms it can see your open tabs.

Then ask it to work with pages already open in your signed-in Chrome profile. Begin with a summary or comparison you can check against the source.

EXAMPLES TO TRY

Useful work, using context you already have.

These are example prompts for pages open in your Chrome profile, not built-in integrations with the services named.

RECONCILE

Pull invoices and orders together

“Review the invoices and recent orders in my open vendor accounts. Make a cited table with vendor, date, amount, and status; flag anything missing.”

PREPARE

Build a meeting brief

“Brief me for my 2 pm customer meeting using the CRM record, project updates, and latest email thread. Cite sources and list open decisions.”

COMPARE

Check price and availability

“Compare this monitor across my open store accounts: current price, stock, and delivery estimate. Link sources and don’t place an order.”

TRIAGE

Review issues and draft next steps

“Group urgent support tickets by customer impact, check the related account pages, and draft suggested replies for my review. Don’t send or update anything.”

KNOW THE CONNECTION YOU’RE MAKING

Browser access is real access.

An authorized agent can inspect and operate your connected Chrome profile. Browser tools can expose page content and sensitive cookies, storage, and other session data, and can perform consequential actions. Browser f6n does not ask for confirmation before every action.

Choose an agent you trust, review its approval request, and follow its actions. To stop the browser connection, disable or remove the extension from chrome://extensions. Requested page data passes through the relay to your agent. The relay does not persist page contents, screenshots, or browser-tool results beyond the bounded command lifecycle. Your agent provider’s handling is separate.

IF SOMETHING LOOKS OFF

Check the popup first.

Sign-in expired: open the popup and sign in again.
Reconnecting: check your internet connection and use the popup’s retry action.
Browser unavailable: open Chrome, keep the connected profile online, and ask your agent to check again.
