This is an awesome extension. A must have. An indispensable addition to your browsing experience and your privacy needs.

It only needs one thing: The ability to save container files. I want to be able to close a container, save its tab names and URLs in a file, and have the ability to get back to it when I need it again in its own window. That would allow me to just close a container I am not using at the moment and come back to it when I need it, saving maybe 90% of my memory.

Otherwise, impressive work. Thank you for your dedication!
