Works well. This seems great if you're using containers as a way to keep certain websites and account info quarantined in a container where it can't be read by other sites. Support for containerising based on regex pattern matching might be a good advanced feature.

I created an "untrusted" container and it does not work.
Works fine on the default containers even after I renamed them but not with selfcreated.

Please enhance the extension with an option to automatically add a rule if I open a website in a container. Copy pasting URLs into the extension consumes time.

This is a great extension. Manually changing the containers was a serious limitation for me. This perfectly isolates my work, banking and personal surfing.

It will be absolutely flawless even if you implement a very rudimentary wildcard support.

Something like (*.google.com) should work for:

maps.google.com
mail.google.com
plus.google.com

To limit the complexity, you need not support partial wildcards, like (m*.google.com) or wildcards in the suffix (example - google.* for google.in, google.com etc).

Good luck! :) Hope to see some sort of wildcard support in future updates.

Can you add wildcard support?

Instead of the current container assignment process which is quite basic today (hopefully it will improve), this addons makes the process so handy and mostly, easily maintainable. Thanks and long life to Firefox Quantum with Containers :)
