@leocg My complaint was Opera keeps a tab open for every webpage I visit even after I exit Opera. The next time I open Opera I get another new tab plus any I have not manually closed. The only way to not having them is to manually close them one by one. Any other browser when closed kills the tabs and it starts fresh when opened next time. The text instructions in the advanced controls was as clear as concrete, made little to no sense. More than half of the tabs have no preview which makes them useless. I got the tabs turned off finally. Thank you for your help, Steps to repeat, open Opera 20 times to 20 different websites and you get 20 tabs mostly useless.
