Please be aware that version 8.0.5 broke the Proxy per container settings!

Works properly but it would be a lot better if it allowed me to automatically assign a container based on the full URL regex instead of the domain name only.

The problem is: I use some sites for both personal and work purposes. One of such sites is GitHub. All repos are hosted under the same domain name github.com, and the repo is selected by the URL path.

This addon can only assign all those repos automatically to one container. Which then poses a problem when e.g. I click a link to a work-related repo and it automatically opens it in my personal container and I obviously can't login. So I have to force a different container manually and it is annoying.

This extension works more or less as expected, with one minor gripe.

I have reddit set to always open in a container, but I don't always want links opened from it to open in the same container.

I want to be able to click the type of container it's in and remove it, without having to copy the url and open the site in a new tab. Ideally this would pretend to be a self-referring link.

Should this functionality be added, I will adjust my rating to 5 stars.

I'm using the containers mainly to separate business and private browsing. Works smooth and effortless.

One of the best addons for today's internet.

Almost perfect. We just need a way to open sites in containers specified directly using Firefox command line options or with custom URLs.

E.g. Having a Windows shortcut that will open a site in one container and another shortcut that will open it in a different one.

This is unintentionally a very good tool for systems and there doesn't seem to be any real limits to how many accounts you can have. The only issue we've run into is the limit of tab colors can make things confusing, and I can't see why there isn't a custom color option unless I'm just not seeing it.

The idea of having separate containers for different online activities is great, but it's annoying when you create new containers and they disappear when you change something on the settings and the fact that you can't import your stored data into the containers unless you do it manually...

Has done what it's supposed to do so far. A caveat though: when I've set a site to open in a container, I can't revert that change to it to open without a container/in a default one.

I like idea that Mozilla tries to move some of the power user functionalities into add-ons making the browser more lightweight by default.

But I really missed this feature, when it was removed and just found this add-on today.

Isolation of trackers, always a good thing! Would be 5* if it were possible to manage the stored data for a particular group of containers, Shopping, News, Google, etc.
A news site that downloads 50 or more, highly intrusive and persistent cookies and trackers will need "cleaning" far more than my "Work" tabs that are typically Linux and FOSS technology which (in the main) seem to use minimal cookies.

It's good but I wish there was a way to put always put all subdomains of, say, google.com into a container automatically, instead of having to add a rule for each subdomain separately.
Ublock Origin and similar add-ons allow the use of wildcard characters which make it easy to filter all subdomains of a site at once. It would be good if this functionality was added to Firefox Multi-Account Containers.

Essential to segregate cookies from Google, Facebook and other spying corporations.

Very close to perfect! A lot of great features! Excellent for both security and privacy. Just a couple of points keeping it from 5 stars:

1st: We need an option so that all tabs set to open in a container by default won't prompt the user to ask if they want to open a link in its assigned container. It should just do it.

2nd: "The Manage Site List..." menu needs an option to manually enter a web address. Currently the only option is to use the address bar button while navigating, but this can break some re-direct heavy sites. Slack logins, for instance, may go through several different corporate domains in an instant and will break in horribly painful ways if one of those URLs isn't allowed to open in the container holding the login cookie.

3rd: Mozilla VPN is a good idea, but its implementation would be less vulnerable to traffic profiling attacks if it were on by default on all containers and each individual container had a separate opt-out option instead of the current enable option. I'd also like if the service weren't tied to specific Firefox accounts, or had a multi-account payment plan, so that I could use it on my work and home accounts at the same time.

4th: This is just a wish-list thing, but I'd absolutely adore it if you allowed us to use third party VPN logins instead of Mozilla VPN. This would be really great for tunneling into VPNs tied to router networks in the home or at work as if the user were physically on location. A lot of companies do this for security and including this could really help adoption.

Address at least the first three of these and you'll get five stars!

La extensión es excelente una de las mejores para esto, pero por favor ya arreglen el problema que cuando se cierra el navegador y no escondí las pestañas de un contenedor al abrir el navegador, abren como pestañas normales y no en su contenendor.. Es un incordio y dan ganas de dejar de usar esta extensión.
