On my Android, Brave gave a different fingerprint both times I visited.

The site thinks both times was my first visit.

The site believes I have either a 4 core or 2 core cpu. I have an Octa-core.

Also, it shows a different display size both times.

Nearly all sites like this can do nothing without javascript turned on.

I'm curious to see how Librewolf is, but that will wait until after work.

Edit: Librewolf does indeed produce a different fingerprint each time. It also didn't give up my location like Brave did on my GrapheneOS phone.

I have since changed the timezone on my phone to a country to the South within the same timezone so the clock remains accurate.
