when i open opera there is random pup up page appears that i dont realize. its small and its in the back of my opera page. the problem is when i close opera pop-up remains and opera recognise this as ı close opera with 0 tab. (i am using so many tabs and not closing them until i finish my job). my tabs gone and there is no recover for this. i cant find my tabs one by one its almost impossible. this happens for a while and resetting opera didnt work. i need help.
