Full disclosure: I miss Tab Groups! Like, REALLY miss them!

That being said, I've learned to live without them. Multi-Containers (from what I understand) may well supplant and/or replace Tab Groups some day, but until then the functionality it brings surpasses what Tab Groups originally did.

Placing websites in specific containers allows for multiple sessions within the same window, making it much easier to switch between multiple accounts without any complicated fiddling here, there, and everywhere; and as someone who maintains multiple e-mail accounts on the same service, it certainly beats logging in and out repeatedly! The additional benefit of reducing and/or negating online fingerprinting/profiling also adds to the usefulness of this add-on.

Highly recommend it, and hope its future is all but assured

RIP Tab Groups, until you get brought back from the dead :)

Je m'en sers principalement pour dissocier les réseaux sociaux du reste de ma navigation et cela fonctionne très bien. La procédure pour ajouter un site à un container n'est pas forcément toujours évidente mais heureusement ce n'est qu'à faire une fois.
Quelques fonctions qui pourraient être très utiles :
- Des containers exclusifs : les liens cliqués externes aux sites listés dans le container s'ouvrent dans le container par défaut.
- La possibilité "d'envoyer" un onglet dans un autre container.

Great add-on that has really helped me with the corp implementation of SSO cookies - one for prod, another for dev/stage environments - on top of the daily use to separate sites (banking from reddit, etc)

The only thing that is fundamental and that is missing now in Firefox is ability to show only one container at a time. Similar to Tab grouping that has been disfunctional from FF57. Power Tabs is nice add-on for newer versions but it's that's much bugged it can't be used.

Very handy and useful to log in with your different accounts (professional, social media etc...)

Does exactly what I need it to--keep logins for multiple "personas" using the same services separated. This is a huge time saver!

Simple et facile. Un must have !

Very useful for multiple logins and for keeping trackers under control and preventing them collecting your entire online world! Would be nice to have the option of syncing settings via Firefox Sync though if you wanted to use that.

Si vous tenez à votre vie privée c'est l'application idéale au quotidien.

It's a nice way to categorise my tabs without using multiple accounts. I just wish it could sync your settings across installs.

Luar biasa, lebih dari Incognito

More flexible than the Facebook Container and similar extensions. Easy to set default containers for various sites, which will keep them contained. You can also revisit some news site inside the Facebook Container to be able to use the embedded comments functions if so desired. I still recommend Facebook Container for basic users, but this extension gives you more control and customization options. Well done!

Works exactly as intended! It functions seamlessly within Firefox, and it was quite intuitive and easy to set up exactly how I wanted it. It also works flawlessly with other add-ons I use like "temporary containers" and "cookie auto delete."

Great add-on. Much more flexible than switching profiles. My wish list is to be able to assign a default container per window.

This works really great. I just have one bug to report. If a container is hidden, and I choose to move tabs to a new window. The tabs open in a new window but each of the tabs are duplicated once. It's a bit annoying but surely fixable.

Do his job properly and unintrusively

I find container tabs separate my online activities pretty well and make me worry less about my privacy and security online. I think this is a great feature, one of those that keeps me coming back to Firefox.

This does exactly as it describes. It's fairly easy to open or create new containers. That said, I would like to see a few changes to make it even easier to use.

Right now, when you create a container, that's all you can do on that screen. You can add permanent sites to the containers. You must open the site in the container, then check a box. In one way, this does prevent any errors due to mistyping, but it would be handy if it could search my history or bookmarks and find sites to add as permanently in the container.

It would also be great if there was a "containerize this site" button. Essentially, use the current site as a sample to make a new container and permanent rule.

Additionally, it would be helpful if pre-configured lists (e.g. all social media sites) that could simply be imported for this purpose.

Excellent concept, and works great. I just wish there were some (programmable) hotkeys for opening and closing tabs for containers.
