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!

没有multifox好用，原因有两个，1：右上角看不出来当前是哪个标签身份。2：在当前标签身份新开标签页时，不能默认为使用当前身份打开标签，全都变成了默认标签。

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.

Just what I need. It will be really good if the colors are customisable, I found the provided colors are too bright and distracting.

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!

Very usefull when combine with Containers Sync. I hope it will have option to re-posittion Containers in the future. Thank you.

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.

I really like the extension. It would be very helpful if one could synchronize the containers via "firefox sync".

Edit:

I have managed to "sync" the container settings manuel. I installed Linux and wanted to use the same containers as before with Microsoft. For this you only have to copy two files:

1. "containers.json" (Microsoft: user - AppData - Roaming - Mozilla - Firefox - Profiles - xxxxxxxx.default)
2. The "storage.js" File from @testpilot-containers (Microsoft: user - AppData - Roaming - Mozilla - Firefox - Profiles - xxxxxxxx.default - browser-extension-data)

Close Firefox, copy and replace both files and restart Firefox. This worked for me.
