I love it... incredible

This lets me compartmentalize my browsing. I can sandbox different domains so that data isn't shared between them. This feature should have been built into all browsers long ago. Given the currently weak state of online privacy, it's refreshing to use a browser and add-ons built by a company that cares. This add-on is simple to use, but I think it would be a little more intuitive if all actions were available through the drop-down accessed by clicking on the Multi-Account Containers icon. In any case, this will forever be a default add-on for me in all new Firefox installations.

Incredibly simple and powerful. I use containers to isolate google and facebook, and it was very easy to set up.

Simple and intuitive solution to sound data management. Yet again showing us how Mozilla is committed to data privacy and an internet based on the users as the customer, not the product. Thank you.

I love this add-on. One of my go to whenever I bootup a new computer. Something to improve could be:
- Save configurations somewhere so its linked to my account. I have to manually add the same configuration over and over again when I configure a new computer.

c'est cool

Outstanding extension - HIGHLY recommended. Isolate your browsing correctly and efficiently and enhance your capabilities of containerization. This is a must have app. They recently upgraded it to include preference sync!

So useful, now I just need a keyboard shortcut to open new container tabs!

It's fantastic but the fact that the setup of Containers (names and assigned websites) does not sync between accounts is a huge drawback!

pretty useful

Using this is way better than using different browsers to keep your sessions separate. A must have for anyone who has to juggle between different accounts for a given web site or web app.

Suggestion: When we bookmark something that's in a container, it would be nice to get asked if we want the bookmarked URL to always be opened in a the same container. This way we don't have to always think of manually putting it in one.

Easy to get started, provides different containers by default but can be adjusted to personal needs.
The different containers allow to log in to the same webpage with different user-accounts.

Super cool add-on. Helps keep me organized.

This feature is THE reason I've switched back to Firefox after many years on Google Chrome. Extensions that leverage this feature to give you additional privacy (Google and Facebook isolation) is great. I even use an extension at work to open a new container and log me into multiple accounts without having to log out first.

I really hope this feature gets implemented in other browsers because it's as revolutionary as tabs or private browsing mode.

Installed it in order to keep two Google accounts open and ended up finding more and more uses for it. Incredibly easy to create new containers and manage multiple accounts.

Super useful!
