CCleaner removes my favorites and my extensions in Opera 20

Since I updated to Opera 20 and use CCleaner my favorites are gone and my extensions are gone when I restart Opera 20 again. I am able to restore my favorites but I have to go back to adblock website and down load my extensions each time.

Is Opera 20 a dev or beta version?

Latest stable release is 19 I think.

I think it probably still is a beta. Opera 20 is available from Opera. My Opera 19 updated itself 2 days ago to opera ver. 20.0.1387.24. It also now has a Bookmark Importer under 'More Tools" but it is grayed out. Probably grayed out because the bookmark importer will soon be in the next update.
