Thank you for this. Just a couple of notes for anyone passing by

• This uses python3 - if you have Homebrew you can
  • Install python3 with brew install python3
  • Usage is python3 check-firefox-passwords.py

This script assumes you downloaded sorted_unique_cf.txt from the master branch. In case you just cloned https://github.com/pirate/sites-using-cloudflare/ you will need to

• Download this script as a sibling to where you cloned https://github.com/pirate/sites-using-cloudflare/
• change line #19 to open("sites-using-cloudflare/sorted_unique_cf.txt")

Finally, on OSX logins.json is under ~/Library/Application Support/Firefox/Profiles/<some-identifier>.default - I changed Line #12 to profiles = os.path.join(os.environ['HOME'], 'Library/Application Support/Firefox/Profiles/*/logins.json')
