Okay, so it seemed like the change has been rolled back. The popup window asking me if I want to restore pages is back again, and I assume that, if the browser crashes again before I can click “Okay”, then I lose all my tabs.
Can we please either please stop asking, or make it a configurable option? If people don’t want their tabs to restore, there is an option in the settings where they can tell the browser to only open the new tab page when the browser starts.
