Very nice, maybe some features:
- setting a container as default when opening new general tabs
- integrating history for every container
- make access to some containers pin protected

très bon module, mais quelques bugs. Il faut prendre un peu de temps pour bien le régler une fois qu'on l'a pris en main.
Le dernier soucis rencontrer c'est une page qui s'obstine à s'ouvrir dans un container A (car configuré par défaut pour celui ci) alors que j'ai manuellement et exceptionnellement sélectionné un container B

It is great for keeping my different browsing separate to help ensure web-sites aren't tracking my unrelated activity. The only issue is that some websites don't like to open with the default container, but I think that has more to do with the website than the extension.

The idea is great, but there is some problems with it.
Firefox has two different mechanisms for data isolation:
1. Different Firefox profiles
2. Containers that can be used within the same profile.
+ Additionaly we can use different OS user profiles.

It would be better to be able to open different tabs or windows within different Firefox profiles or OS profiles.

It works pretty well, but the "Always open this tab in new container" is glitchy
One of my tabs just wont open right now. And it's very annoying when I need to open in another container and there's nothing in settings where I can either remove that property or change it.
So I would advise steering clear of that feature.

Would like to have the ability to switch between tabs opened in each container (especially with a keyboard shortcut), would also be great to use as the foundation for tab grouping for open bookmarks.

Let me know if either of these exist if I'm missing them!

Il y a des problèmes de connexion lorsqu'on connecte 2 comptes (gmail, par ex.) dans deux containers différents, c'est assez laborieux et ne fonctionne pas toujours.

It lacks the option to input manually an site into a container so one doesn't have to first open the site and then make it into the container.

I think the only thing it needs to be perfect it's some new icons

Очень круто! Полезно если есть различные аккаунты... Так же жду поддержки вашего VPN в России... Поэтому пока 4...

Good concept. I had to remove a star because:
1. one cannot clear data of a single container without destroying it;
2. it doesn't group tabs by container;
3. limited personalization options (8 colors and 13 icons, really?).
