Using FF 72.0 & Multi-Account Containers 6.1.1 it lasted for about 15 mins then broke. I cleared all my history including the cache and after that container assignment in the URL tab disappeared forever. It previously appeared using a mouse right click on the tab. Tried bouncing everything and reinstalling it...still dead. I can manage the containers but putting a tab in one is gone. Finally got it working by completely reseting FF and reinstalling it along with my other add-ons.

no possibility to sync with other instances of firefox. Its useless this way. The whole syncing makes for me only sense because I can use the browser at home and at work, but i dont want to mix the contents. Because Firefox does not support multiple profiles, or does not have a user friendly support for profiles, the multi-account-containers would be a good workaround, but if you cannot sync containers, this addon its useless.

In times where privacy both matters and is at risk, it's great to keep your logged in sites in something that looks like a different browser (the containers). Besides it also allows to have different accounts on a given website and be logged to both of them at the same time, just in different containers. This is the best thing Mozilla could have made for browsing. A fantastic enhancement on Private Mode (which is a bit like a container too, but it does not preserver your logins, history, etc., whereas containers do.)

Makes using this functionality easy. Needs Firefox Sync! Need to add ability to set a preference for each bookmark, which container to open in when clicked!

Extension indispensable pour qui possède plusieurs comptes sur le web. Avec lui on peut créer autant de containers que l'on veut, les nommer chacun par l'adresse mail souhaitée ... et ouvrir 2 , 10 comptes gmail simultanément (ou autre fournisseur de mail), mail ou site quelconque où l'on accède par au moins 2 adresses mails différentes.
Problème, les containers créés ne sont pas sauvegardés, donc on peut les perdre.
A peine signalé et c'est corrigé, désormais c'est sauvegardé avec sync et donc disponibles sur tous les pc, Merci :)

This add-on is basically the only reason I use Firefox, and it has so many issues that I frequently contemplate leaving it.

Syncing across multiple devices (Windows, Mac, Linux) just doesn't work. It doesn't. On Windows I have 4 duplicate "Home" containers that reappear every time I sync. On Linux I get over 10,000 "Personal" containers. On Mac, who knows. I delete the extra containers (or try, on Linux), and next time I sync a device, they're back! It's maddening!

Now on Linux I've uninstalled and reinstalled a dozen times, and it won't add my custom groups. Where did they go? Why is this so hard?

good

this extension has been very helpful. i see its true value everytime i use firefox.

An app that is not only great, but also necessary!

very helpful
