Extension Usage Instructions

Privacy Crawler recursivly follows links from page(s), and produces a report showing

- what cookies first appeared at what page, together with their domains, expiry times and values;
- what Javascript is accessed that could be used to fingerprint the browser.

**Warnings and recommendations**

When starting to crawl, this extension will **delete all cookies** in the current environment. It is recommended to run crawls in incognito mode to avoid logging you out from all of your sites.

It also patches the Javascript environment to

- determine which functions and objects are accessed;
- make time faster, since some trackers are set to load pixels and Javascript after a delay, and crawling takes too long if we waited in real time.

Therefore to avoid strange behaviour on sites, it's recommended to only have this extension enabled when you are crawling.
