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.

Simply awesome! Makes organization effortless. Thank you Mozilla

Work very well!

Very useful for development

Me encanta, al principio si no eres alguien que enserio se dedique a la computacion puede ser algo confuso, pero cuando lo entiendes y ves su potencial ¡ufff! Es genial para gente de negocio evitando que te veas obligado a usar 2 navegadores, así un contenedor para uso personal y el otro para el de trabajo.

This is a really helpful tab organizer. I really like the 'always open in container X' option and the quick opening a tab in a container by long-clicking on the plus; with those two it's easy to stay organized in containers as I visit lots of sites. It's great to be able to have different accounts open in the same browser, especially since the containers are so easy to distinguish visually.

Funktioniert wie erwartet. Mehr kann man da nicht sagen.

A melhor extensão que já usei. Possibilita navegar na internet usando várias contas e perfis diferente. Gosto dela.

Love being able to keep things sorted out into categories, and the segmentation of all the tracking data sites collect is a nice bonus. The setup process could be a bit easier (getting all your common sites sorted) and I would appreciate a way to completely disable the "default" container. Also this NEEDS sync support. Each device I use FF on I have to recategorize all my sites. Mobile support would be cool also, but I'm not living and dying for that one.

This is an excellent idea and is really useful and well implemented, after the initial few bugs that were in the beta. My only request is for the ability to re-arrange the order of the different containers, and to add a wider variety of icons ;-)

Very helpful, works like a charm. Setting up containers could be a little more intuitive sometimes, but most of the time this, too, works great.

It works and is super easy to use!

Muito útil! Tenho que gerenciar várias contas por conta do trabalho e o Multi-Account Containers facilita minha vida.

Could not use a browser without this now. It makes it easy to have multiple sessions logged in in a single window.

effective

Wonderful, lovely. Thanks to this, I don't have to use different browsers for different purposes. It combines great with Cookie Autodelete addon, which honors container tabs to kill cookies selectively.

Containers are more convenient than having multiple profiles in different windows. Must have for testing when you need multiple sessions to test web software. It is easy to open the same site in different container right from tab. Also there is useful feature to configure some sites to be always opened in specific container by default. This way i separate personal sites and sites for work.
