Site Receipt от arena tech

Site Receipt shows what happened during a browsing visit in a simple receipt format. After you leave a website, it can notify you with a score and store a local receipt you can open, copy, export, or download as a PNG.

Receipts may include:

Active time and wall-clock time
Network and third-party request counts
Recognized tracker request counts
Cookie changes and new cookies
Local/session storage growth
Popup attempts
Permission-related API calls such as notifications, location, camera/mic, screen-share, and clipboard
An A–F site-conduct grade
Site Receipt is privacy-first: no account, no analytics, no remote code, and no browsing-data upload. Everything is stored locally in Firefox.
