All tabs are removed on restart
I have a very annoying bug.
Sometimes, if not always, when my computer restarts - all of my Vivaldi tabs are removed.
How do I solve this issue?
Looks like your Vivaldi was not ending correctly.
Please try to deactivate in chrome://settings/system the "Continue running background apps when Vivaldi is closed"
And one some Windows 10 Hibernation kills processes too early.
Perhaps you can deactivate the Quickstart of Windows.
