Is there a maximum number of bookmarks or history for Firefox Sync?

This is a follow-up of this question. So there is no limit for saving bookmarks in Firefox, but is there actually a limit in Firefox Sync?

I have heard something like this.

And if so, does it mean I may loose some bookmarks when I sync them between devices? Or actually have some bookmarks only on some devices?

Same question for history entries etc.

Solution 1:

Oh, actually the answer seems to be on support.mozilla.org:

There is only a limit for the payload used for synced tabs and a date/time range for the history. I don't think there is a limit for the bookmarks, but bookmarks are synced in chunks of a few hundred items (200), so it takes some time to sync a large amount of bookmarks.

So basically, it does not seem to be the case. It only takes some time and cannot sync hundreds of items at the same time.
