Multiple default containers: suggest more than one container in Multi-Account Containers Confirm Navigation tab

[jjmzn]

Current behavior: When there's a default container for a website and that website is opened, Firefox asks if the user wants to open that website in the current container or the default one.

Problem: When there are multiple containers that the user uses to open a website frequently, if the one that the user wants to use at that moment is not suggested, they have two options:

1. Open a new tab in that container, then try to enter the website again;
2. Open in the container they don't want to use, and then reopen the container they want to use.

Suggestion: allow setting multiple containers as default and then show buttons for each one. Some ideas:

1. Add a button for each container;
2. An option to select one of the containers from a list;
3. Buttons to recently/often used containers for this website.

The first suggestion would be something like:
