I may be feeding the trolls, but not only is there a sync mechanism, at least with Firefox you can self-host[1] such a thing, thereby
doubly ensuring the data isn't used for something you disagree with
If you're going to say that Firefox doesn't care about having users, point out its just stunningly stupid memory usage, blatantly stale developer tools (that one hurts me the worst because the Chrome dev-tooling is actually open source, so there's nothing stopping them from actually having Best In Class dev tooling other than no-fucks-given), or the har-de-har-har that comes up periodically of bugs that have been open longer than a lot of developers have been alive
