Multiple Windows, Single Session
By: losnappas
Turns out pressing Ctrl+Q or closing from the menu does this (and works better). (Relaunch closed windows on next startup. Experimental. Addon button closes windows for good.)

Is Multiple Windows, Single Session Safe?
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.
Multiple Windows, Single Session requires a few sensitive permissions. Exercise caution before installing.
