How does Phishing and Malware Protection work in Firefox?Phishing and Malware Protection works by checking the sites that you visit against lists of reported phishing and malware sites. These lists are automatically downloaded and updated every 30 minutes or so when the Phishing and Malware Protection features are enabled.[...]Before blocking the site, Firefox will request a double-check to ensure that the reported site has not been removed from the list since your last update. In both cases, existing cookies you have from google.com, our list provider, may also be sent.

If you could just write down all of the phone numbers you’ve called in the last two years together with time, duration and location of the calls made, that’d be super.
