You could use regular Syncthing for any device other than iOS. And for iOS you could use Sushitrain/Synctrain: https://github.com/pixelspark/sushitrain

Sushitrain/Synctrain might be what you looking for. It’s a libre and new app for putting syncthing to iOS: https://github.com/pixelspark/sushitrain

I get that some things like screen resolution and basic stuff is needed, however most websites don’t need to know how many ram I have, or which CPU I use and so on. I would wish for an opt-in on this topics: So only make the bare minimum available and ask the user, when more is needed. For example playing games in the browser, for that case it could be useful to know how much ram is available, however for most other things it is not.

I know that it has that in theory, but my Firefox just reached a lower score on https://coveryourtracks.eff.org/ (which was posted in this threat, thanks!) than a Safari. Firefox has good tracking protection but has an absolute unique fingerprint, was 100% identifiable as the first on the site, as to Safari, which scored a bit less in tracking but had a not unique fingerprint.

It would be nice to hammer a manually created fingerprint into the browser and share that fingerprint around. When everyone has the same fingerprint, no one can be uniquely identified. Could we make such a thing possible?

But why would any browser accept access to those metadata so freely? I get that programming languages can find out about the environment they are operating in, but why would a browser agree to something like reading installed fonts or extensions without asking the user first? I understand why Chrome does this, but all of the mayor ones and even Firefox?

Hmmmm, money

Almost no corporation has benefits operating in a liberal/left country, they are harder to exploit and make profit of. Why would they promote things like worker protection, parental leave, unions, reducing their own rights to favor the society, paying for healthcare etc? Edit: Wording
