My Desktop firefox has 8 open tabs and they do not sync on my android browser. Even pressing the sync now button does not show the tabs in the homescreen. I am running a private mode on the desktop. Does this affect syncing in any way? Also, on the android app, native videos do not play. I can watch the same videos in the youtube app but whenever i try to play them on firefox, it crashes.

Actually cookies must be enabled for the data to sync, so yes it is expected for private tabs not to sync. Also when you say native videos do not play, can you provide an example and the type of device that you are viewing them from?
