I have a web page that I can't close . It pops up every time I open opera and no matter how I close it the next time I open opera it is there again. It is a web site I was using yesterday, it is the confirmation page. Any idea how to get rid of it ?

Mine is just the same. I have happily used Opera for over a year and this includes Gmail but for the last few days I am getting the same message. You are right, it looks as if it is back to Firefox if no-one can help.
