Speaking of mullvad. I recently learned about mullvad browser, which is basically tor browser minus connecting via the your network. This is interesting because the tor project has put the most effort into fingerprinting resistance. If you care about privacy and you have a customized browser, you're likely uniquely finger printable [1]. If you don't want to connect via tor, there's no excuse not to use the mullvad browser. (Doesn't require you to use mullvad VPN; comes with the mullvad plugin, disabled by default, to optionally use mullvad encrypted DNS. Last point, I wrote to the tor project and asked "is it possible to use tor browser minus tor network", and they responded "that's the mullvad browser", so this isn't just my recommendation)
