I user 1 browser windows for each monitor, first had like 150 tabs and second had 10. After finishing work I closed second window and then first window. When I logged in the following day, Opera opened just one tab in the main window and after Ctrl - Shift - T opened second window without problems. I lost all my work related tabs and it is a dealbreaker. I can't use a browser if it randomly closes tabs. I don't want to search tabs in history because some are opened every day, some once per week/month. Can I somehow get my tabs back?
