Hello, Since the upgrade, sync is broken. I cannot send tabs to or from android firefox. I used to use to collobarate with my linux desktop, now cannot. Linux desktop is syning fine. But the firefox android settings have always said: "Last synced: never" which means bookmarks, sharing tabs, etc. are all useless now. this totally kills firefox for me. i have readded and removed and readded and readded the firefox account/pairing with android. no difference. This was a major upgrade without choice, not just a rolling bugfix and feature build. Very upset and thinking of leaving my favourite browser
