Fantastic addon providing much needed functionality for containers that is inexplicably missing from Mozilla's Multi-Account Containers addon. The user interface for editing the rules is a little lacking, with its tiny window, but that may be a limitation of Firefox.

With curated domain pattern lists, such as those created by another reviewer of this addon, Andrei Shevchuk, it becomes very easy to keep certain privacy invading organisations shut inside their own container.

life saver

I really can't explain how thankful I'm with this extension available. I just can't comprehend why would Moz never implement this feature. I really really can't comprehend. -_-

So far the best part of this plugin is that it literally does everything people are begging Mozilla to do for containers to make it better.

So far so good. This is exactly what I needed. It looks like you can use * as a wild card so I've got a rule for *.google.com, *.facebook.com and *.amazon.com that have been working as expected. Thanks!

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
