This is truly empowering for those of us that need to juggle multiple accounts. I work for an MSP and have several clients with the same providers. This extension allows me to open those different accounts along side each other.

One thing I would love to have is integration with Firefox Sync. I setup 8 different containers so far. Then I went to my laptop and found I have to set them up again. Firefox Sync would be delightful.

Love this. I use it all the time. I wish I could reorder my list of containers and change the keyboard shortcuts, though.

I LOVE THEM, BUT they make Firefox crash when closing.

Great add-on. One of the reasons to use Firefox over other browsers. Ideal for testing e.g. Office 365 with regular user accounts on one set of tabs and an admin account on other tabs. I would love to see the container configuration being synchronized via my account, just like most other Firefox settings.

Makes life much easier for me managing multiple credentials for the same sites. The only complain I have is that I can not go in and manually edit the rules to open tabs.
If the tab preferences could be synced to be used across devices it would be really great.

Great idea, but it should be synced accross devices

Best container managing addon I found until now. I love the "default feature". Only drawback, it seems to map whole (sub)domains to containers. I would wish for the possibility to map some pages and their subpages on a domain and/or subdomains to a different container.

An use case example is Wordpress. If making changes to a site it would be nice to have the backend in one container while the live site is in another. But after mapping the backend to "work" container the site also always opens in "work" and vice versa. Of course I can temporally choose another container, but making this permanently changes it for the whole domain and not only the page and its subpages.

An good example how this could work better is "Dark Background and Light Text" (https://addons.mozilla.org/de/firefox/addon/dark-background-light-text)

Anyhow, thanks for this marvelous addon.

Great Concept - Could Have Better UI Integration

I love the concept of containerizing web browsing. I'd love to see functionality expanded to allow Firefox to automatically asks users what container new tabs should be opened in vs having to right-click on the add-on Icon manually and select the new tab that way.

Очень полезное дополнение.
Требуется возможность синхронизации между устройствами или хотя бы экспорт-импорт настроек в файл.

Нужна синхронизация и бэкап настроек. Пока что дополнение на 4-ку, есть к чему стремиться. Если не увижу стремлений в течении года, снижу оценку.

Alles funktioniert sehr gut. Schade dass die URI-Container-Zuordnung nicht zwischen verschiedenen PCs synchronisiert wird.

Please have Firefox Sync synchronize the settings for MA-C (separate from extensions sync)

Good to work on Multi Mail Account. Don't Work on Facebook Multi Account.

PLEASE SYNC WITH FIREFOX ACCOUNT ENTIRELY INFORMATION. THEN, THIS WILL BE BEST, I THOUGHT.

Super

Overall I think this is a great add-on. The one thing I wish it had was settings interface where you could manage what sites open in what tabs. If it had that this would be a 5.

I'd give you the fifth star if containers could be synced between different computers.

Very useful, nicely separates different web activities. Only missing is synchronization via Firefox account.

It's a very practical add-on. No complaints whatsoever. However, I'd like to have an option to sync settings across multiple devices. This is a huge deal-breaker.
