I just upgraded Ubuntu from 21.10 to 22.04, and now Chrome (deb), Thunderbird (snap), and FireFox (snap) will not open nor save to any network drives (a home Ubuntu server); all of these apps read/saved to the same server before the upgrade this afternoon. So, "me too", but also it may not be limited to FF, snaps, or even Mozilla, since my Chrome install behaves similarly.
