multi-account containers is too limited for me.

This add-on is getting there but needs regex support so that I can direct www.google.(co.uk|com) and others to a "tracking" container and console.cloud.google.com to a "company" container (because they use two different google accounts).

Other people have mentioned wildcards, but that's going to be difficult to code effectively - regex will be a better option.

To dev: "cookie autodelete" addon makes a great working model of how to demonstrate regex and wildcards effectively to the uninitiated.
