The browser identities

Your browser is invisible_playwright: a real Firefox that a site sees as a person at a computer. How to drive a page (finding a page, the order to try things in, what a page can tell) is in the browser server's instructions, which your system prompt carries. This file is about the identities. Use the browser when a task needs a website; for a plain download or an API, exec with curl is simpler.

Identities

A browser identity is one person on the web: its own profile, cookies, logins and fingerprint, kept on disk between uses.

• browser_identity_list shows the identities, which are open, and how many may be open at once.
• browser_identity_create makes one, closed. Give it a name only: it then leaves through this computer's own network, which is right unless the person asked for this one identity to use a proxy of theirs.
• browser_identity_launch opens it on your desktop. The first launch of a new identity can take minutes.
• browser_identity_close closes it; its profile, cookies and logins stay.
• Every page tool takes the identity_id of an open identity, and acts on that identity's one page.
• Reuse the identity that is already logged in to a site instead of making a new one, and keep one identity per person or account you act as: two accounts in one identity are one person to anyone looking.
• A second identity is for what must not touch the first. The usual case: signing up somewhere and needing a mailbox for the verification. Open a throwaway-mail site in another identity, take the address, type it into the form in the first one, and go back to the other for the link.

Close an identity with browser_identity_close once the task no longer needs it, before you answer: an open browser holds memory on your computer.
