Re: "Retain tabs from previous session" doesn't work.
So, rather new on MAC, and the issue with lost tabs when closing is annoying. I use Opera as work browser ... lost a lot of things.
But most of the time it was because of me, not Opera.
- as a windows user, i know that closing an app from "x" will close it. unfortunately, not on MAC. on MAC you are closing the window, not the app.
- if i right click and close the browser and then reopen, the session will be restored.
I think this is not a bug, but an uncovered OS behavior that influences the behavior of "Restore Previous session". Thus making it rather unreliable.
