Bit of an uphill fight with captchas everywhere. Do people here conduct all online activity over VPN whenever possible? Only for the sensitive stuff? Or perhaps the inverse because the bank already knows you? Maybe when travelling or getting around region blocking? Something else?
The one provided by my work aside, I realized that I don’t have any consistent rules around using VPN. Except sometimes, you know, when downloading ISO’s for my favorite distos.
What makes you think the Tor Browser and Mullvad Browser are not made by “security professionals”? Have you used either of them? They already have defenses against font, screen resolution, and many other fingerprinting vectors.
Also, “plausible and believable” fingerprints were already considered by Tor Browser and Mullvad Browser, and I believe are actively in use by Brave Browser. I forget why Tor Browser and Mullvad Browser opted to instead give everybody the same fingerprint, but there was a reason for it.
