I tried everything you suggested. It doesn't work. I try to explain myself better (sorry, I'm not an english native).
I have the Google personalized home page as my home page (the one that loads when I open Firefox), and since when I installed CCleaner to see it personalized I have to access. Even after having told CCleaner not to delete any of the Google-related cookies (I preserved any cookie that belongs to my personalized home page).
Another aspect, that my be useful, is that sometimes the page is still logged and works just fine, but then when you close and open up Firefox again it all goes back to unlogged and not loading. In the meanwhile I have never run CCleaner, nor opened it.
I tried to uninstall it, and it all goes back to normal. That's why I'm telling you about this problem. I would like to solve it, since this is one of the best file cleaners I've tried. Thanks for your time, anyway.
