Its a great plugin idea but it doesn't really work as intended. After setting up Zen, leaving idle for a day and returning back to to it, Zen erased by pinned tabs on click. I could click any pinned tab and it was like closing them. This behaviour was reproducible until I deactivated this plugin.

It seems to have stopped functioning properly in Firefox version 141.0
I still see my list of containers to push tabs into but they don't open in the associated container anymore when visiting a page.
Edit: The list of containers I had in the editor was gone hence it stopped matching new tabs to the rules I had in place. Very obnoxious.

Between this extension and Firefox's native cookie separation for all domains, your private browsing experience becomes effortless.

i used to painstakingly manage containers with the default container extension. no longer needed!

Much better than multi account container addon

Perfect replacement for Acid Tabs when migrating from Chrome

Needs an option to save container/URL rules to sync across devices. Very annoying to have to manually set up rules with every new browser install.

Good, but unmaintained...

Can not sync container rules between devices.

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.

Adds an essential feature to container tabs: The ability to always open sites in a specific container tab based on relative paths! Like for Azure devops, I use:
@dev\.azure\.com/client1/.*
@dev\.azure\.com/client2/.*
Really great for contractors who frequently switch between numerous accounts.

Yeah, super great! 5 stars for the great functionality, though probably only 4 stars total due to overall polish/ease-of-use and lack of approving bugfix PRs!

There's also only 1 example provided for their regex flavor. (It's a little odd, but simpler. Forward slashes are fine, and you don't have to worry about text before the domain. Maybe I'll get around to making a PR with more examples soon.

Edit: Never mind on that! It seems the dev may have forgotten about this. There are several open PRs (some years old) with fixes and feature enhancements just waiting to be reviewed and merged.

I know the interface is buggy and that the extension hasn't received any updates the last three years, but it really helps when one wants to automatically open a container with a given URL (unlike Firefox built-in feature, that only filters by domain).

Amazing, especially if you need to deal with subdomains, basically this fixes some issues of 'Multi-account Containers', making things a lot easier/better.

There are a few issues with regex, it seems that you can't use regex flags (like insensitive match) and if you try to add a URL that has upper case letters Containerise forces it to lower case.

Example, add this as a new rule in Containerise:
@addons\.mozilla\.org\/en-US , Test

Save it, and you'll notice that the 'US' will be automatically converted to 'us'
So when you have a URL with upper case letter like the current addons mozilla page you would need to do something like:
@addons\.mozilla\.org\/en-\w{2}\/ , Test

Not ideal, because it can match stuff you don't want to.

Aside from that, this is great.

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.
