I really enjoy having certain websites open up in specific containers all the time (social, banking, news, etc..). It takes some time initially to get the bulk of your most frequented sites setup. But once you do, it's rocking.

Cool extension for accounts segregation. But lacks following:
- open URL in previously selected container without asking if I selected "Always open in ";
- open URL containing subdomain in container if I configured that container for main domain (example: shop.com, hardware.shop.com).

The only features I would like to see in this add-on to give it 5 stars:
- the ability to re-open tab in a specified container
- the option to have the sessions associated with add-ons be global or have the sessions be different for each container

The always open this site using a container feature is very helpful. If only there's an easier way to open the current page in another container instead of having to open a new container tab and copy paste the url.

That exclusive Facebook Tab helps you maintain your privacy.

Very useful for work computers.

Ótima extensão! Fácil de usar e muito útil para separar a navegação em determinadas tarefas

I love, love, love containers. Even when a site I need multiple accounts for has its own multi-account management, containers is better... and most sites don't.

It's perfect for separating out multiple accounts for testing a site during development; it's perfect for separating tabs out by category, each with a color stripe to remind me what they're for. It's basically perfect -- add in a self-destructing private container, maybe, and custom icon support, and I'd say it *was* perfect... but using colors with the simple dot icon is almost as good anyway.

Thanks, Mozilla. :) Containers are awesome.

Works great for me. I now can separate my work Gmail to my personal Gmail on different tabs without linking my Google accounts.

Very usefull for someone who has multiple accounts for their job

It is extremly helpful for web development/testing. With "Multi-Account Containers" I can run different identities within the same browser window. Great job! Many thanks!

I think it does what it says it does and I enjoy using it.

Literally the best add-on I've ever installed. Except the one that changes "Trump" to "Drumph", obvs..

Enjoying this for ease of use and privacy! Putting in Multiple firefox users within separate tabs would be the next step!

Hugely useful, especially when used together with Cookie AutoDelete

Exited about this feature, it's future development, and its deeper integration in the Firefox browsing experience.

Needs a bit time getting used to, but once it's working, it reliably does what it's supposed to do. Would be nice though having a small UI for managing pages associated with existing containers, so far this feels somewhat "magic". :)

2 years ago (5 stars): Game changing App. Has been the reason I have switched back from Chrome to Firefox.

11 July 2020 (1 star): What have you done? Which use case / UI designer did this? Utterly rediculous. I now have to multi-click navigate menus to open a new container. Why was this a good idea? You could at least have allowed CTRL+Click to open a new tab/container without going into an additional menu. I moved from Chrome because of this extension - I will move back if this doesn't get fixed in a matter of days.

Note to developers: This is a "convenience" add on, try not to make it less convenient!

Issues that need fixing:
+ Sync is inconsistent - needed to turn on/off to get to work?
+ Can't manually order containers in list.
+ Order of containers in list is not maintained from machine to machine on sync.
+ Assigning shortcut keys is broken - doesn't reassign the keys.
+ Assigning shortcut keys is broken - Assigning new keys after sync - only allows two keys to be assigned > then page refresh for additional 2 keys, etc.

Roll this update back, then if you want to do something useful - get it working with startup pages properly. e.g. so that I can open multiple Gmail accounts in different containers as startup pages and I dont have to open them all individually. Also it would be useful if the containers could be sorted into a custom order (rather than just order they were added), e.g. drag and drop to sort containers in list.

16 July 2020 (5 Star): Thanks for sorting single click container open - back to being convenient again now. Remaining issues need fixing and some of the additional features would be nice.

I really want to like this plugin, it provides functionality that really should be built-in to the browser.

However, the user interface and management features are lacking.
- I can't just add websites to containers. I have to manually navigate to each website and then I can add it to a container. If I only want that website opened in the container, I have to navigate there AGAIN to check the box.
- I can't import or export lists of containers and domains. I have to start over again every time I install the plugin.
- The plugin loses track of website favicons so always shows broken image icons instead of the favicon.
- The UI for removing domains from a container has lots of visual bugs making it a challenge to use.
- Once you set a domain to always open in a container, there is no way to force the domain open in a different container. You have to remove the domain from the container completely and start over again.

Hey Mozilla, theres a ton of potential in this feature. Please don't let it die of neglect!

Simply awesome! Makes organization effortless. Thank you Mozilla

Work very well!
