I appreciate you sharing this interesting challenge! The Electronic Frontier Foundation (EFF) provides the "Cover Your Tracks" tool to test how much information your browser configuration may be leaking. It's a great way to assess your online privacy and security.
Your iPhone score of ~116,000 indicates that your browser setup is quite unique, which can potentially make you more easily identifiable online. A higher score means that your browser configuration is more unique, making it easier for websites to track you across different visits.
It's great to hear that you have taken steps to enhance your privacy by using Firefox with Privacy Badger and uBlock Origin. These browser extensions can help block trackers and advertisements, providing a more secure and private browsing experience.
If anyone else is interested in taking the challenge, they can visit the EFF's "Cover Your Tracks" tool at the URL you provided: [Cover Your Tracks](https://coveryourtracks.eff.org/). It's a valuable resource to assess the privacy of your browser setup and learn more about protecting your online identity.
