When I exit Opera 9.5 I often have many tabs open. At next startup Opera will open these sites up again. After running the latest CCleaner, Opera opened with no tabs at all. I lost many hours of Internet research. Does anyone know if I can get these back? Also a suggestion. I don't think this should be default behavior, as I was unaware this would happen, and I suspect many new users would also not expect it. Thanks for any help.

Ok, look, you made a noob mistake. If u spend a lot of time for research u should never just leave tabs open and than use it for a next time. Did u heard for option in every browser, called Favorites? Also use it.

CCleaner, what i know from my experience, clean all history on your browser. That also happened with your tabs too. And, as far as i know, u can't get yours tabs back. Sorry! If I am wrog, maybe someone else can correct me and help you more.

P.S. my englisch sucks, sorry for that!
