i use it in brave, i think that most of what is added to tor browser is for the viewing clearnet via tor use case not for darkweb sites

it works great, and anyway, you gotta use SEPA or Revolut or something anyhow, really you only hide your IP from the robosats webserver, so i see no reason to be worried about the missing security features between tor browser and brave - and brave is pretty hard core antifingerprinting and whatnot

i have a xapo card anyhow, couldn't be happier with it except for being able to send sats to it via LN

unless you are going for full on trace avoidance the whole nine yards just use brave to access it
