(sorry for bad english) After closing girefox while on window mode, (accidentaly) I reopened it realising none of my accounts were signed in and all websites (youtube, adsense, gmail etc) needed google verification. and they were treating me like i was visiting first time after download. Why is that? Now I have to bring all my data back!!!???!! I am using Windows 8.1 and the latest version of firefox. No other browser installed...
