@belkaspeleo Yes, it seems that there's something in the online account, maybe some old settings or something else that creates some kind of conflict. In fact if you create a new account at the end of the day you'll put the exact same things you had in the old one (bookmarks, settings, passwords, etc.) as it's what you have saved in local and that obviously were mirrored online, but somehow it will work flawlessly. However when it freezes it seems to repair the account too and it will solve the problem.
