The greatest firefox add-on i ever installed. It helps me to move content from one account to another, to separate my identities (work, baking, personal).
It gives me a better sense of security.

This is like my most favorite Firefox addon in the whole wide world (next to an ad blocker like uBlock Origin). Save me the hassle of having to create separate Unix accounts to browse using other identities. My current wishlist for this addon: a keyboard shortcut to open a new tab using the same container as the currently opened tab.

Multi-Account Containers make it so easy to keep your browsing habits separated. I'm opening University websites, banking and shopping tabs at the same time. Awesome!

Thank you mozilla for this awesomeness!

This will get five stars when it will sync my containers across computers.

This is a game changer extension for personal privacy. Preventing tracking from websites like Facebook and Google across other websites we visit. The only thing this extension is missing is a way to backup manually created containers and integration with Firefox Sync.

What a great idea to try and separate browsing tabs from prying sites!

I am really enjoying this container tabs add-on, it has a very useful functions such as separating accounts, defining a specific container to open specific websites, hiding an specific container...
The reasons I'm not going full 5 stars here are in my next paragraph babble, but it's still a REALLY GOOD add-on!
I'd love to see just few more features such as sorting container tabs in new windows and being able to "mute" or "offline" certain tabs without hiding them (and also the I could choose what tabs to un-hide and in which - or a new- window) much like how you used to be able to choose what to restore after a crash. Being able to open bookmarks on containers also, and setting up a default container... Also, being able to save settings with my firefox account for cross-device ease and consistency!

Really useful for web development

For me this is a must have. Such a great extension and the ability to make custom container categories is awesome. I only wish the containers/rules synced accross devices.

Would love it to have options in the context menu to open links in containers

A really clever, simple add-on that I'm surprised no one has ever thought of before. A lot more convenient than switching to a separate Private Window any time I don't want to be tracked.
Works especially well in combination with Mozilla's Facebook container extension too, to combat those pesky Facebook trackers.
If I have one complaint, it's that you can't directly enter a container tab by right clicking on a link from your bookmarks toolbar! You would have to do a Google search for it and then right click on the link, which kinda defeats the point of having bookmarks if I want to use Container with it. Please fix this Mozilla!
Otherwise, an excellent add-on.

Une excellente extension permettant d'utiliser pleinement la fonctionnalité de conteneurisation de Firefox. Pas de bugs à l'usage.

Effective at what it claims to do. Easy to use. Have had no issues with it.

I'm really enjoying containers. I do a lot of Cloud and internet work and previously was opening normal and Inprivate Edge, IE, Chrome and Firefox sessions to be able to log in to many systems to avoid the browsers caches clashing. Now I just use Firefox, it simplifies it no end.

Easy to apply. Looking forward to the enhanced security provided by the separate containers.

Too buggy to be usable for privacy. "always open in " shows checked, but domain isn't actually associated w container. No way to have links to non-associated domains open in default container. "open link in.. " doesn't work. No easy way to associate many domains to a container.
