It seems possible that Brave are building Brave Pro, which looks like its a subscription based service of some kind. A note on the Android implementation of the project reads (GitHub link):
"Implement the required runtime changes (profile settings, chrome flags, group policies, etc.) with the appropriate values that enable the Brave Pro experience. Using Brave in this mode with its default settings and making changes to the Brave Pro defaults require an active paid subscription.
When the browser has no active credentials for Brave Pro, the panel UI will promote the service and include the initial payment CTA. When credentials are present the panel UI will include the appropriate toggles for making changes to the default settings."
It also links to a private Google Doc.
Which privacy tests? Are you referring to the ones conducted by a Brave employee where he compares browsers in their default setup? Since Vivaldi asks you on first launch how you want to configure it, he decided to choose the worst settings and use that for the comparison.
To be fair, Vivaldi selects the worst options by default and when you’re not careful and just click continue, it will choose them.
That is a valid criticism of their setup process. My guess would be that “No Blocking” is set as the default option to ensure that the average user clicking through the setup process does not encounter difficulties accessing cerain parts of the web and mistakenly attribute it to Vivaldi being an inferior browser. Like all browsers, their target market will be people moving from the market leader, which is currently Chrome. As is well known by now, Chrome does not provide users with these protections by default and so many of its users do not know or care about them and just accept the experience as normal. Vivaldi and others therefore base their default installation options on what a Chrome user would expect, as opposed to what is objectively the best setup for privacy. If a user does care about their privacy, they are almost certainly going to select another option during setup.
I think a fairer and more relevant way to compare these browsers would be based on their optimal, in-house GUI setup options, without going into things like Firefox’s about:config or extension stores. To me this is a more realistic way to present information to a user who is concerned about their privacy and looking for a new browser. The assumption that someone concerned with their privacy would just blindly install a browser and never enter the settings or make any adjustments is a pretty silly one. Vivaldi would still not be the best, but the tests would better reflect its ability to offer privacy to its users.
Not a brave employee and barely affiliated with them. Also Firefox browsers come out on top still. Vivaldi is missing much of the fingerprint disception features of Brave or Firefox. It is also closed source meaning it isn’t a good choice for privacy anyways. All around a shit take when it is obvious Vivaldi isn’t built for anti-fingerprinting. I am by no means a supporter of Brave, I stay far away from it and its shit.
“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.”
It is ~95% open source. The remaining 5% of closed source changes are to the web-based UI.
Does that change the fact that Vivaldi is not a good privacy browser? Its content blocker is weak, its based on chromium which is affected by MV3, it can’t protect screen dimension fingerprinting, or canvas fingerprinting, or containerize cookies, or block 3rd party scrips and frames, or standardize specific settings like Firefoxes RFP, etc. Not a good privacy browser. Use a fully open source browser.
