Vivaldi allows you to save your current open tabs as a named session, so you can open the tabs whenever you need them.

To save all open tabs in one or all windows as a session:

1. Either, go to the  Vivaldi menu > File > Save All Tabs as Session or type “Save All Tabs as Session” in Quick Commands.
2. Give the session a name.
3. Decide whether you want to save tabs in the current window only or from all windows.
4. Click Save.

To save only some tabs as a session:

1. Use the Ctrl / ⌘ / Shift key to select the tabs you want to save as one session.
2. Then, either right-click on one of the selected tabs and select Save # Selected Tabs as a Session from the context menu or type “Save Selected Tabs as Session” in Quick Commands.
3. Give the session a name.
4. Click Save.

To open a saved session:

1. Either, go to the  Vivaldi menu > File > Open Saved Session or type “Open Saved Sessions” in Quick Commands.
