Normal anti-fingerprinting measures aren’t effective against companies with lots of resources. Does setting the security level to “safest” actually thwart more advanced tracking? The ideal case is that it would make a user look like everyone else who browses on that OS and browser in safest mode.

Based on the [Tor Project’s wording](https://support.torproject.org/tor-browser/features/security-levels/) it seems security modes are primarily made to benefit your security and are less about anti-fingerprinting, though I’d assume it helps with anti-fingerprinting since websites are far less capable to do things in general without JavaScript, certain fonts, etc.
