    I just upgraded from Opera 50 -- which kept crashing -- to Opera 51. And all my bookmarks are gone. Several YEARS worth of bookmarks are gone. This has never ever happened with any previous upgrade and I've been using Opera for more than four years. Is there ANYTHING I can do or am I totally screwed?
