What some probably consider a privacy nightmare is a Chrome feature I like very much: It syncs all my history, bookmarks and passwords across devices via my Google account. That's especially convenient whenever I get a new device.
Firefox's sync feature is comparable except that it's not a privacy nightmare because it's end to end encrypted and you can also run your own sync server if you want to.
It would have taken you less long to duck/google that than to type that comment, so I feel like I'm missing your point. Did you mean to emphasize that you don't mind sharing data with Google, or was it really just asking about if firefox sync exists?
Please don't discourage people from asking questions directly to other humans. Google results can be surprisingly obtuse, and no matter how much information has been written about something, there are always cases where the clearest and fullest answer for a given individual comes from a direct response - and even if that's not the case here, people certainly don't need more excuses to shy away from asking questions.
Is there something comparable for Firefox?
