ua-client-hints VS user.js

The Client Hints specification covers a lot of this already - https://wicg.github.io/ua-client-hints/#content-adaptation-u... ... DPR, width, and viewport-width are already available in some browsers. Hopefully other hints will be available soon.

I encourage you to review the decision making and engage in the discussion here: https://github.com/WICG/ua-client-hints

chrome is starting to implement UA-CH, which splits up user agent info into individual headers sent by the client: https://wicg.github.io/ua-client-hints/

As a Firefox/FreeBSD user occasionally annoyed by this nonsense, but not being knowledgeable about modern web standards evolution, I wonder if https://wicg.github.io/ua-client-hints/ will fix this by killing User-Agent headers.

ua-ch might reduce the amount of data browsers send, though it's gonna take a while to move away from regular user agents: https://wicg.github.io/ua-client-hints/

There is a JS companion to this proposal that splits up the information in a similar way

Re: firefox and privacy, if you want to use firefox for privacy, consider using https://github.com/arkenfox/user.js . There is a case to be made that Firefox (with arkenfox's user.js) is one of the best privacy-respecting but still fairly usable browsers.

For extensions, I recommend people follow the recommendations[1] in the arkenfox repo and either harden their firefox or use librewolf. Umatrix is unmaintained since 2019.

For macOS : Thunderbird and you can harden it even more with this : https://github.com/arkenfox/user.js

only arkenfox

This article is shit. https://github.com/arkenfox/user.js/ is what you want.

If you make time to dig through settings and change them away from their official use (99% of users don't), then you should use a customized setup (in this case, a user.js). That way, you're good to go no matter what Firefox fork you use.

> Firefox remains a stable option to come back to everytime

Don't get me wrong, I've been using Firefox for the last decade and I don't intend on using anything else for the foreseeable future, but Mozilla has no idea what they're doing with Firefox nowadays. Firefox View is the most useless thing I've ever seen, that expiring "independent voices" theme picker was some weird hippie stunt[1], the latest UI redesign which split the tab from the window looks hideous, and it's not like Firefox doesn't have things you can tweak for a more private experience[2]. I miss Firefox Test Pilot where they tried out different new features, I found a lot of them to be very useful but sadly lots of them didn't make it.

Like others have said you can customize the browser to the point that it doesn't even look like the default anymore. Or customize it to maximize privacy.
