Very important to note that it is not the same profile as Tor, it’s its own unique profile. It’s also important to note that this is the case with Arkenfox/Brave as well, any anti-fingerprinting measures tend to make you more unique. This is the explainer text we’re proposing for the website if it makes more sense, or if you/anyone has feedback:
Without using a VPN like Mullvad, Mullvad Browser provides the same protections against naive fingerprinting scripts as other hardened browsers like Arkenfox+Firefox or Brave can provide. Mullvad Browser provides these protections out of the box, at the expense of some flexibility and convenience that other hardened browsers can provide.
For the strongest anti-fingerprinting protection, we recommend using Mullvad Browser in conjunction with a VPN, whether that is Mullvad or another recommended VPN provider. When using a VPN, Mullvad Browser creates a “crowd” of other users for you to blend in with, which is the only way to thwart advanced tracking scripts, and is the same anti-fingerprinting technique used by Tor Browser.
Note that while you can use Mullvad Browser with any provider, other people using your VPN provider must be using Mullvad Browser for this “crowd” to exist, something which is more likely on Mullvad VPN compared to other providers, particularly this close to the launch of Mullvad Browser. Mullvad Browser does not have built-in VPN connectivity, nor does it check whether you are using a VPN before browsing, your VPN connection has to be configured and managed separately.
