How do I recover history

I have had issues previously with reopening Opera with tabs from previous session. Generally, I can go to History and "Restore tabs" or whatever the option is. This "disappeared" tonight. It does not show the option. It only shows a list of history entries, no option to
"Restore". I really try to close all open Opera windows except my "main" window with my important tabs before closing Opera which seems to have caused the problem in the past. (And the only reason I close Opera is because it is using too much memory which has a tendency to cause my computer to abort programs.)

Tonight, I cannot restore my history/tabs. I do not remember what exactly I might have done to cause this. Is there any way to restore my tabs/history? Granted, I probably don't need all the tabs I had, but many of them are important, business/government/tax related.
