Im not too sure if Vivaldi is supposed to statup as recent tabs. It seems that every time I close vivaldi and then open it up again all the recent tabs open up as well. is there a way to stop this from happening?
It seems that currently there's no way to change that, neither through the UI or by other means. But it's quite likely this option will appear eventually, even though they probably went for what they felt the majority of their users would prefer, meaning to keep the session instead of starting with a clear one each time.
