Awesome add-on. Pretty easy to configure and I really like that websites can be set to open by default in a specific container. What would really make it a 5-star add-on for me, would be built-in automatic sync for settings across devices for the Firefox account.

Pretty good extension, but doesn't work with all websites.

I always have to re-login into Twitter when I closed FF and WhatsApp is always opened in the default container.

Need a way to have certain containers act as private tabs - IE it doesn't appear on your history.

Makes browsing even more more secure by separating your bank accounts infos, from your Facebook infos, from the rest. Much better than the "private" browsing concept because the cookies for each of these world remain after each browsing session, so you don't have to start over again each time. Much better also, because switching between each container is automatic (if desired), so you don't have to remember who goes where : in itself this is a great security feature. Of course, as the name implies, if you have many accounts for a given site, it also allows you to stay logged-in as these various accounts all at the same time, which is great. Loses a star because setup is not smooth, but once everything is set-up, Firefox Multi-Account Containers becomes totally transparent and a joy to use.

As the title said, this is by far the must have extension. Just a little bit uneasy to setup. But once set, everything will work like it should.

Worked as intended and quite smooth ( 2 weeks usage, as of now. No hang/slow down yet) but again syncing across devices should be a great plus

too many acounts can get very confusing, hoping to get a few utilities or tools to make the organizing easier

As a software dev that has to open up sites in both admin mode and user mode, the multi-account containers has been great!

I use this add-on mostly for the feature to pin certain sites to containers. I wish it would gain the features of Context Plus to move tabs between containers as well, but for now I use both.

Just added this add-on, can't wait to put it to use. I give it 4 stars off the rip just because the idea itself is pretty damn good! We'll see how well it works for me and actually helping me distinguish stuff throughout my day that's work or home.

It works very well, nothing seems to overlap by mistake. What I really wished to have in the future are private containers. Basically, a container that uses incognito, but still having the ability to tab browse beside other non-incognito tabs. Sadly, after the quantum update, one of my favorite add-on became unusable and the developer can't do much about it.

Excellent add-on. Does what it says, but its a bit fiddly to set-up. The only sensible option seems to be to delete all cookies and create the containers in the order you want them to appear in drop down menu. Feature suggestions:

1. Sort containers in drop down list without editing JSON file or deleting all cookies and creating containers from scratch in required order;
2. Organize container contents without looking at each individual cookie (I hear the latter ability will soon be removed by Firefox changes);
3. Allow sync across devices (with option to auto-delete cookies which become container-less as a result);
4. Allow containers to be sync'd with bookmark folders to simplify management and make it easier to remember which websites belong to which containers (websites used in two containers will appear in two bookmark folders);
5. Option to auto-delete cookies in default (no) container;
6. Option to auto-delete cookies not in container specified for that website.

j'aime beaucoup, mais souvent quand je souhaite lancer un site qui se trouve dans un autre container que celui dans lequel je lance la requête, je me retrouve avec le site qui s'ouvre en deux fois :(

Dommage, j'espère que ce bug sera vite fixé car l'app est vraiment cool!

+ un mode avancé pour pouvoir ajouter nos propres règles qui ne sont pas forcément basés sur le nom de domaine

This effort, container tabs, seems to be off to a good start. Missing though is that there seems to be no way to verify that container tabs are actually isolated from each other. Also, what advantage is there, if any, to have a window that only contains a single container type , such as "Personal" over a a private window containing the same number of tabs with the same content, where the tabs are not allowed to be container tabs. The container tab idea is great but more documentation and proof of their effectiveness would make them more useful.

Easy to use, I really wish I could sync container settings between my computers though.

This extension works great! Subtle icon, doesn't slow down my browser, and works as expected once it is set up. Note: each website does need to be opened in the proper container the first time to set it up correctly.

I would love to be able to set up website blocks/timers, so I can block going on social media when I should be working. I haven't been able to find the extension I was using for this before.

This extension is great for keeping your various on-line accounts separated. In the world of multiple Google, Microsoft, etc. accounts, using this extension allows you to be signed in to all of them at the same time (in separate tabs).

I would like to see a few more features around managing the containers - e.g. being able to re-order them to my liking. Also, allowing custom colors and icons.

I would also like the ability to right-click a tab that is open in the "Default" container and switch it to another container.

Finally, adding the ability to sync my container settings across machines would be the icing on the cake :-)

Keep it up!

I love how easy it is to use. It would be a full 5 stars if you could convert or reopen a tab in the container. Otherwise, it's a great app.

Great way to isolate accounts from each other. The 'always open in container' feature is nice. I do wish you could make shortcuts to new tab containers, though. If you've got work & personal accounts for particular services this is a must-have plugin.

There were some issues earlier like reset back to default containers and loose my options, but it worked well for the last weeks.

**Removed text**, found the feature to list all domains and edit the domain list in the current version. Great!
