They’ve been chipping away at Tor browser for a while now. It’s well known that it can be fingerprinted now. I think it was like last year or something where they made a change they lied about and got caught. Eventually enough people had it that someone finally tested the damn thing and demonstrated the flaw. The tor browser people said too bad we’re not changing it. It was something that was intentionally introduced to enable fingerprinting on tor. The network itself seems very good but tor browser itself, not so much

I’m not saying to stop using tor, but you really should diversify your shit. Look into i2p, set up a reticulum node, get multiple options ready. The great danger of tor is that damn near everybody involved in darknet stuff is using it, which means it’s an incredibly appealing target for the feds who have demonstrated they are not to be trusted
