PrivacyTests.org is run by a Brave employee (Arthur Edelstein)

He is extremely smart person though, just that money can taint any good intentions easily. Especially in a very "shark" ecosystem.

>Full disclosure and transparency

>(Updated June 2022)

>This website and the browser privacy tests are an independent project by me, Arthur Edelstein. I have developed this project on my own time and on my own initiative. Several months after first publishing the website, I became an employee of Brave, where I contribute to Brave's browser privacy engineering efforts. I continue to run this website independently of my employer, however. There is no connection with Brave marketing efforts whatsoever.

>I am committed to maintaining this website's accuracy and impartiality. It is my goal not to promote any browser here, but rather to offer objective test results for all browsers that encourages a general improvement in privacy across the industry.

>By keeping this project fully open source, I endeavor to provide the maximum possible transparency and verifiability of the tests and results. Anyone who wishes to check the results can clone the git repository and run the browser tests independently. Ideas for additional tests, or code (pull requests) for additional tests that provide further insight into browser privacy, will be gratefully accepted.

Here is one more source - one of the academic studies I mentioned. https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf

It is not a comprehensive argument that "brave better", just that it sends less tracking information by default. Still, I think that's an important metric.

Brave's adblock is actually based on the filtering used by ublock (check out the filter list pages for both browsers!). However, it is inferior to ublock on Firefox (or librewolf) as there is more sophisticated CNAME uncloaking (among other things) on FF/LW.

Brave does do CNAME-uncloaking.

I thought you were saying firefox CNAME-uncloaking is somehow better than brave's.
