I upgraded to a new Surface Pro 12 and now when I launch Firefox it won't open my previous tabs and windows even though I've checked the box "open the previous windows and tabs" under the General/Start Setup. On my previous Surface Pro 3, I never had an issue with this. Am I doing something wrong..? Also when I click on the time in the lower right task bar, it would open the time plus a calendar. Now with the Pro 12 I get the time and a notifications window and no calendar. Is there a way to change Firefox to the way it was on my old Pro 3..?
