Overheat1859 Vanadium's approach to anti-fingerprinting is discussed on these parts of the site:

Numerous fingerprinting tests are not reliable as they rely on a pool of results of the userbase of the website, many of which use very different setups in comparison to the average person. Some browsers also do fingerprinting protections differently i.e. Brave randomizes data while Tor tries to keep it the same as possible.
Likewise, the only other browser the project recommends is Brave. It preserves mobile Chromium's security posture while adding additional state partitioning, anti-fingerprinting improvements and the most advanced content filtering engine. Vanadium has greater security enhancements like MTE support in production but needs to catch up in some areas. The new filtering for Vanadium is a part of the improvements.
