As others have said, Mullvad is pretty close to (if not at) 100% guarantee… No personal info whatsoever is required to be given when you sign up (including email address or payment information; you can use Monero if you want), so there isn’t really anything that they could give to authorities even if they wanted.
Even if they did keep logs (which im 99.9% sure they don’t), all that would show is an IP address, and from what I understand based on past precedent, that is not enough to identify a person on its own. But IANAL.
To be fair, free-mp3-download.net is not a URL I would voluntarily go to. I mean seriously…
You may have turned on a setting in Firefox that is meant to obscure your browser fingerprint. For me, it seems to force more captchas for me.
I kept the feature on though, because when I signed into Google and got the notification of a new sign-in on my phone, it thought my OS was Windows NT (it’s Linux) so it seems to at least kind of work.
I forget what the setting was off the top of my head (in about.config I think), but could look into it if anyone is curious.
Edit: went and found info on it. It is not just “Enhanced Tracking Protection.” It is specifically about blocking your browser fingerprint: https://support.mozilla.org/en-US/kb/firefox-protection-against-fingerprinting
Dwarf Fortress is quite the rabbit hole. It’s so much more than just a game. The complexity of the simulation has actually made me wonder about simulation theory IRL.
It’s mind blowing.
