This doesn’t seem right. 1 in 6.2 billion for Firefox on an iphone, not including ip/network uniqueness?

Seems more plausible that anti-fingerprinting is throwing it off?

Some of the data seems straight-up wrong.

I know this computer has more RAM than reported and it's definitely not on a 4G network either.

The APIs it's relying on to show you that information do implement some anti-fingerprinting mechanisms - things like available memory will be put into rough buckets rather than returning the exact amount you have.

It got facebook pixel wrong. I see zero DNS requests to facebook.com on NextDNS

That panel reconstructs what a pixel would send from your own browser values, locally, and never makes the request. NextDNS seeing nothing is the tool working exactly as designed.

Yeah seems like it doesn't account for anti-fingerprinting at all.
