Yeah, it seems that they even acknowledge that Tor and Mullvad are better for extreme threat models.

"The only browsers that can provide sophisticated fingerprinting protection against advanced scripts are Tor Browser & Mullvad Browser.

If you have an extreme threat model (Ex. Political dissident, journalist, or if you are in some other kind of high risk situation), please use one of those browsers."

I suppose we’d have to commend them for being fair.
