I have mine set to do this automatically, though it sometimes fails, I think after some updates (though I've not looked into it enough to be confident this is the pattern). In these cases reopening the tabs/windows with ctrl+shft+T reopens most, bit not always all of them, and the ones that are lost seem quite arbitrary (it might be something I've had open for days or longer, or something I was looking as a short time before restarting).

PSA: Chrome's session restore function should not be trusted as a way of accurately maintaining state between restarts. I've not noticed the same with Firefox and Brave, though I don't currently use them as much (I'm slowly moving over to using mostly Brave or Firefox, I've not yet decided which…) so maybe they are no more reliable in this area.

Indeed! You can even configure it to open the last set of open browser tabs as per default, saving you a `ctrl+shift+T`.
