It is almost what I want, but I have one feature that this extension does not cover.

To transit to 'No container' or another container from a specific container when no other rule matches.
Default container feature seems similar, but I want to apply the rule only when using specific container(s).

If it is implemented, the extension will be perfect for me.

Hello, can you add an autodelete cookie/ cache feature to a default container. This is a great extensions, thank you for the good work.

Justo lo que necesitaba, una meta-extensión para poder encarcelar conjuntos de sitios web.

You can assign a container to specified website(Which multi account container still CAN'T). So your container changes when a website does not assigned it. To do that enable "Match domain only" and "Default container" option in addon's setting. You can use this rule "!sitedomain.*"(without quotation) assign any site to container. Example if we assign google's domain to google domain we should assign "!google.*" rule to Google container.
Bad thing is addon owner is not active well so it's not frequency updated. There is fork called "bifulushi" that updated frequently and has active development.

Its a best help, functions have perfection. Thank you

Great job with this extension. Deeply grateful for the lists provided in the comments below. I think I'd like to have a separate container for when you create a "new tab" that could be different than the "default container" which I've enabled in the options.

This is one of my favorite add-ons. Miles better than the Multi-Account Containers! Really wish there are rules for links inside a container though.

Very nice add on, thanks a lot for this open source work.

Great addon! Keeps certain accounts isolated on different domains

Don't know if the Dev reads the reviews but here's mine. I like this extension a lot, nothing wrong and keeps accounts for example YouTube in its own container, however I have multiple accounts on YouTube mostly for a fresh start away from my main one as its sub box is crowded. When I set YouTube for its container and open another container (I.E. Personal) I want to be able to have that container be exempt from the rule I set for the YouTube container so that it doesn't just change the container to the YouTube container I set.

Totally works, but does not put colored line on tab. please enable the colored tab :)

Very useful addon. I was about to develop something myself but this work extremely well. The mechanism to record new domain takes some time getting used to but is eventually very effective. Might be great to have a way to access the addon settings page from the popup. Thanks for your work on this!
