alt Hacker NewsUnfortunately you've now made an incredibly niche browser, and the lack of those metrics is a good fingerprint by itself. How browsers render SVGs can be used for fingerprinting (even the underlying OS affects this, and I assume you'll want to see those), combine with ISP from IP address, and unless theres hundreds users in every city you're now pretty easily trackable.

If 100 people are using that browser, how will they know which one is me?

Can you provide details on this? And how will they know which OS I'm using (through SVG rendering...)? The UserAgent definitely should not send the OS.

That's already provided whether I use Private mode or not, correct? I can always use a VPN.
There's no problem with having a unique fingerprint. The problem is having a consistent one. Randomize the fingerprint every time and you're fine. The IP address problem applies to everyone, including anyone using tor browser. The only solution to that is not using your own IP address (VPN/proxy). If I were going to make a secure privacy focused browser it either wouldn't allow things like rendering SVGs (which have introduced vulnerabilities beyond tracking) and wouldn't allow much (if any) JS and only a sane subset of CSS.
