foxlend — lend one login to an AI agent Autor: Pooria
Lend the login of one site to an AI agent in its own container, with a scope, a time limit and an allow list. Pages in the container reach only the hosts you allow. Revoke the loan, and the container and its cookies are gone.

O tym rozszerzeniu
An AI agent in your browser can use every site that you are logged in to. foxlend gives it one.
Who it is for: people and developers who run an AI agent in Firefox and want to limit what it can reach.
What it does
A change to Firefox settings while a loan is active: foxlend turns off WebRTC and network prediction for all of Firefox, so a page in the container cannot send data around the block. This also affects your own tabs: no page can start a WebRTC call, for example a video call, until the last loan ends. foxlend turns the settings back when the last loan ends. This happens only when you lend a login.
What leaves your computer: nothing. foxlend has no server and makes no network requests of its own. Loans and the blocked log stay in this browser.

What it does
- Makes a new container named "Agent · <site>", copies the cookies of one site into it, and opens the agent's tab there. Your own tabs stay logged in.
- Blocks each request from that container to a host that is not the lent site or on your allow list, and shows a live log of blocked requests.
- Sets a scope (read, fill, submit or pay) and a time limit for each loan. A foxgate grant with the same scope covers the same hosts.
- When you revoke the loan, or when its time is up, closes the agent's tabs and removes the container with its cookies and site data.
- Can hide the agent's tab, if you tick "Hide the agent tab".

Permissions
- Containers, cookies, tabs and hidden tabs: make the loan container, copy one site's cookies into it, and open, hide and close the agent's tabs.
- Access to all websites, web requests and proxy: block requests from the loan container to hosts outside the loan. foxlend cancels a blocked request, or sends it to a local proxy address where nothing listens (127.0.0.1, port 9).
- Privacy: turn off WebRTC and network prediction while a loan is active.
- Browsing data: remove the container's site data on revoke.
- Public suffix list: find the site of a host.
- Storage and alarms: keep the loans and end each one when its time is up.
