Yep, this is a result of APIs the embedded map uses that are also used for fingerprinting. So, currently there is not a way to allow the map to function and enable fingerprinting blocking.

However, #8787, which is currently being implemented, will enable us to allow sites to use more complex functionality in a way that still protects against fingerprinting.

@cybo1927 also, fwiw, the relevant bits of this change are in nightly currently. I'm able to browse that map with all fingerprinting protection blocked currently. If you're a nightly user, could you let us know if it looks fixed for you too?

Confirmed that this is fixed in nightly, and will be rolling out to other channels accordingly. Thanks again for the report @cybo1927 !

Also, @cybo1927 , you're Brave version is pretty behind. You might just make sure you're on the current stable version of Brave (if not Beta or Nightly). Current stable is 1.8.x, and you're on 1.5.x
