Privacy Crawler

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.
