@fishmom If what you want is to get all sessions (ie tabs) in the new machine (laptop/pc) here is what I did to get all tabs from one desktop to another (this only works for Opera in Windows:
Source has Admin as user, target has User as user (replace as appropriate)
Backup the following folders in the target:
C:\Users\Admin\AppData\Roaming\Opera Software\Opera Stable\Session Storage
C:\Users\Admin\AppData\Roaming\Opera Software\Opera Stable\Sessions
Delete the above 2 folders (Session Storage & Sessions) in the target.
Replace the above two folders with the ones in the source:
C:\Users\User\AppData\Roaming\Opera Software\Opera Stable\Session Storage
C:\Users\User\AppData\Roaming\Opera Software\Opera Stable\Sessions
This way you get all your tabs from the source carried through to the target.
One caveat, you lose the session in the target machine, for me it was not an issue as I just wanted my session carried across.
Hope this helps you or someone else, it's ugly but very fast for the purpose.
Until Opera devs decide to offer Tabs syncing that is...
