I’ve grown increasingly paranoid, at an accelerated rate since 2016. I’m dependent upon the open Internet for communication and general iOS app functionality, since nearly all of my apps are useless without connecting to some service on the Internet. Whether it’s via WiFi or using AT&T, my current wireless provider, nearly everything I send mobily is in the clear. The notable exception is my use of ProtonMail, which encrypts and decrypts locally for email, and Signal, providing the same capabilities for chat.
These following screenshots are Google Chrome, Firefox, and Safari running the Panopticlick web page. The browser apps are all up to date.
The worst of the browsers as far as Panopticlick is concerned is Chrome, the first screen capture. It got no green checks, only warnings (partial protection) and outright red cross marks, an indication of no protection. I don’t use Chrome on my iPhone, so that’s not an issue.
The next entry is Firefox. I had it configured for night mode so I could attempt to match the dark mode I have my phone in. It faired much better than Chrome in this test.
Finally there’s Safari at the bottom. Like Firefox it faired much better than Chrome, and it managed to fair a bit better than Firefox fingerprinting, which was deemed a partial.
I’ve been looking at moving over to Firefox on mobile for a long time, but it has a number of operational issues that keep me from using it on my iPhone. For all practical purposes I’m happy with Safari (although its lack of dark mode is a bit strange), and trust it more than the other two. If I didn’t have Safari (meaning I was using an Android handset) I’d be using Firefox in a cold New York minute before I would ever fire up mobile Chrome. And if anything ever goes sideways with Safari, I’m pretty certain I could live with some of the quirks I found using Firefox.
But for now, it’s still Safari for me.
