I opened Opera today and lost all the tabs I had open. I was not logged in into my google account anymore, I lost my workspaces, I lost my bookmarks, I lost my extensions,... It's as if I had reinstalled Opera. I had the same problem when upgrading from Opera to Opera One so I guess there was some kind of update.
After I logged into my opera account I at least got my history, workspaces and bookmarks back. It's really a hassle to reopen all my tabs I had open to either save a website or join in a later session. Also the Homepage button is missing which I don't like in the new opera.
