I have been trying to switch from chrome but so far no other browser has this feature.
On Chrome I can open a window and have multiple tabs, then I open up another window.
When I accidently close one of the windows with multiple tabs, I want to restore the closed window with the multiple tabs. On Chrome I can go to the history and there is the option of restoring the window I accidently closed with the multiple tabs. No other browsers has this feature. I can only restore individual tabs. So I'm going back to chrome.

Every so often I keep getting "No internet connection" but not problem with 'Chrome. The browser does not respond to any click of the cursor. Have to close browser and restart. I would like to continue using Opera but if this keeps happening will need to switch to Chrome. I do leave open a lot of tabs.
