Librewolf has Resist Fingerprinting which comes pretty far.
Every Librewolf browser uses the same windows user agent, etc. But there are downsides, like time zones don’t work, and sites don’t use dark mode by default.
And even then, EFF’s Cover Your Tracks site can still uniquely identify me, mainly through window size. That’s one of the reasons why Tor Browser uses letterboxing to make the window size consistent.
I don’t know what letterboxing is. But if window size is used to identify me, can’t it be circumvented simply by using the window in restored size, and not maximised?
Your restored window size is even more unique than your maximised window size!
The correct solution is to just not make the window size available to JS or to remotes at all. There’s no reason to ever need specifics on window size other than CSS media-queries, and those can be done via profiles.
Changing the source code of the browser, unfortunately. I don’t know what Tor Browser does or how, but basically you’d have to do about the same as they do.

But the restored size keeps changing - can’t be profiled, right?
And how do I not make the size available “to JS or to remote”?
