Amazing Utility Add-on, especially at work! Auto-sorting works great, really I think this add-on should be rolled into Firefox's core functionality.

L'utilisation des "containers" m'a permis de cesser d'utiliser les "profils" d'utilisateur pour firefox. J'étais obligé d'ouvrir plusieurs instance de Firefox : ce n'est plus nécessaire !

The best extension in Firefox's history.

Firefox Multi-accounts maakt het makkelijk te wisselen tussen accounts bij allerlei internetdiensten. Bovendien houdt het de zaken gescheiden. Gewoon binnen één browser-venster.

01/27/2019: Annnnnd STILL waiting to just be able to reorder my groups in the groups menu. Astonishing that this is still not a thing.

08/20/2018: I have downgraded my review to one star, not because this extension is THAT bad but because of lack of attention to the add-on–especially as one of Mozilla's own add-ons. It is now almost September of 2018. Quantum has been out for how long now? And we STILL cannot do the simplest things like SORT GROUPS. Groups are forever doomed to stay where they are in your groups list when you add them. My groups are in such a FRUSTRATING, illogical order because I cannot move them around or sort them. Zero of the issues below have been touched either. Come on, Mozilla. Don't die on us again. If you're going to take away a bunch of developer functionality, replace it already on the new platform.

To add to the list:
- Please change add-on so that when a tab is assigned to a group that is hidden, the entire group does not unhide and load every single tab in that group. Need the option to keep the tab hidden.

ORIGINAL REVIEW:
This add-on has been a so-so substitute for TabGroups, but certainly not a replacement. Many months later and we still do not have simple things such as:
- tab hiding,
- a way to sort groups in the group-selection menu,
- a way to move an open tab not assigned a group to a group,
- a way to move a tab from one group to another,
- and very few group colors and icons for groups to choose from for differentiation.

Will we see a useful update to this add-on soon? It has potential but is very inefficient in its current state.

What could make this add-on even better is if popular sites opened up in the proper container out of the box (ex amazon opened in shopping without the user having to set it up)

This is perfect add-on.

Great to be able to use multiple online identities freely, especially as a software developer where you need to juggle several for testing purposes. But I just wish this extension had a setting for automatically launching new tabs or windows in the same container as you're already in when you hit Ctrl+T or Ctrl+N. (At least, I can see no obvious way to enable this.)

I recently have been trying to swap from google chrome to firefox quantum. It has worked really nicely but firefox doesn't have the feature to log into multiple accounts, and I wanted to keep my school and personal separate. So I found this and has been using it to do that. One thing I want is the ability to open a new window for single container. It is pretty annoying having to and remember to double tap the new tab button everytime.

Très simple d'utilisation de part l'intégration parfaite à Firefox! Depuis que j'ai installé Multi-Account Containers tous mes onglets professionnels sont isolés. Cela me permet aussi d'ouvrir plusieurs "instances" de certaines applications web gérant très mal les enregistrement dans différentes fenêtres ouvertes en même temps. Continuez comme ca, cet add-on m'est devenu indispensable, merci!

Containers makes Firefox the best internet box!

Funciona muito bem! Deixa tudo separado e muito bem organizado!

This app is great. I use it every day to stay logged into both my work and personal accounts at the same time.

Excellent addon.
But doesn't work since Firefox 89.

Great just misses context button to open current window in another container

It's good start.

The interface could be improved. It's very clunky to add and manage new sites in containers. You can't add currently opened tab website to a group. You can't manually add or edit websites. You first have to open a new container then load the website then tick "always open in ___" if you want it loaded as default. There's really no options to speak of. You can change the name, colors and icons of containers and that's about it. Opening a link in the same container designated for facebook that embeds facebook trackers kind of defeats the privacy. Making the container exclusive to the specified sites as option could help.

As much as I find this addon useful, it's developed by Mozilla, It's no Screenshot add-on. I imagine it will eventually meet the same fate as Tab Groups.

I think that this add-on has a lot going for it but it could use some help like when opening a new tab it had the option but currently when working if I want another tab I get thrown out of a flow having to go and click on it on the other side of the browser or use keyboard short cuts but the period is still on the other side of the keyboard.

Love it. Using it extensively for multiple containers.
Only issue is that it does not support syncing containers across multiple machines. My other plugins get synced but not this one
4 stars due to the sync issue, otherwise 5 start
