How to export cookies.txt
Install a browser extension that exports Netscape cookies.txt (Chrome/Edge: “Get cookies.txt LOCALLY”; Firefox: “cookies.txt”).
Open the site in your browser and log in (YouTube, Instagram, etc.).
On that site’s tab, use the extension → Export / Download as cookies.txt.
Upload that file below. We use it only for your browser session and auto-delete it after 6 hours.
