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

Works perfectly well. I use it together with the 'Temporary Containers' extension when I wish to keep a dedicated container, and it runs better in my experience than the 'Firefox Multi-Account Containers' extension. Nice work. Recommended.

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.

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.

Amazingly useful!
Two issues:
- has not been updated in over half a year
- if a rule matches in both Containerise and Multi-Account-Containers, the tab duplicates :/
