@leocg thanks for the info.
Yes, that's what I do but doesn't the profile folder include other things like cookies and other info? it usually is a very heavy folder to backup and I just want to save/export a few things, not absolutely everything.
It would be great if Opera would let you export just what you select, or like I was saying make the cloud sync work also with a new installation of Opera, removing the need to manually backup the profile or anything. Just have sync save what you want and then reload it in a new installation of Opera upon login in
