I am logged into way too many sites to do that unfortunately. I do use a password manager with a browser plugin to make it easier, but it's still a lot of manual work to re-login to all the sites I use on a normal basis, for both work and home, every time I restart my browser.

Would be nice if there was some other solution, like maybe encrypting the browser profile and then requiring a pin/password/biometric/something to unlock it on each start.
