Some Unity games give following error msg in Mozilla-browsers:
SecurityError: The operation is insecure
For example this game Play SAGA Idle, a free online game on Kongregate, worked fine bit over week ago but then hasn’t worked besides in Chrome and other sites (and in both cases game starts from 0) and Kong support hasn’t replied to any of my support tickets.
Other minor issue is that sometimes (quite often) when I open Unity game I get gray screen and no game screen until after 1 or more page refreshes (Kong claims that its Unity’s error not theirs even no gray screens before Kong did some update to site months ago).
Unity webplayer is latest.
