Sorry I tried to link directly to the highlight but that feature is not supported in Orion:

it is literally impossible to prevent fingerprinting from a sophisticated fingerprinter if one is ever allowed to run.

Certain facets of fingerprinting are impossible to block but fingerprinting uses a hundred data points and randomizing just a few of them can be enough to throw it off, and this is what private browsers do.

Instead of removing or modifying browser differences, or adding troublesome permission prompts, the Brave browser will start adding subtle randomization to some fingerprinting endpoints. This privacy-through-randomization approach has been studied by privacy-focused computer scientists, most recently in the PriVaricator (Nikiforakis et al, WWW 2015) and FPRandom (Laperdrix et al, ESSoS 2017) projects. This is the first time those approaches are implemented in a mainstream browser.

This approach is fundamentally different from existing fingerprinting defense approaches; current approaches attempt to make all browsers look identical to websites (an impossible goal). Brave’s new approach aims to make every browser look completely unique, both between websites and between browsing sessions. By making your browser constantly appear different when browsing, websites are unable to link your browsing behavior, and are thus unable to track you on the Web.
