Great, it works without any problems

Finally, a way to open google.com/maps on a separate container to google.com.

The only thing missing is for the setting to be synced via firefox sync.

Seriously, this should be part of Firefox by default. Easy to use, works like a charm, and even works for bookmarks as well, so there's no need for another extension!

Simple yet powerful extension. It can assign domains to "No Container" and enable a custom container to be the default container. Thank you for making this; it has been an excellent replacement for the official multi-container extension.

Can contain google search from the rest of their services.

simple and effective.

I am using this add-on along side Container Tabs Sidebar and its one of my favorite combos now. It took me a bit of learning on the global and regex patterns but it's working great for my purposes.

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!
