Almost useless as a privacy feature since it does not work in private mode - and doesn't even warn you about it. Clearly, getting container isolation while having web history recorded on your harddrive is a very bad privacy trade.

they changed it so that facebook automatically opens up in a designated facebook container & i can no longer use the addon to be logged into two facebook accounts. it seems there's no way to bypass this

I have add and removed both Multi-Account Containers and Facebook Container several times. Neither seems to function or work with the particular FireFox set-up that I am using (FlagFox, No-Script, Colorful Tabs, Google Translate, WX Download Status Bar). I have reviewed several videos and none of the features function except for creating new containers (neither right or left click within the MAC drop down or the "+").

So far I've added three empty tabs and not been able to figure out how to put the tabs I want into the container.

Très bien mais un gros bug lorsqu'on installe l'extension avec Speed Dial.

Chaque vignette SpeedDial dont l'URL a été mise dans un container s'ouvre dans le container dès le chargement de la page SpeedDial. Comme une nouvelle fenêtre s'ouvre, il est impossible de revenir sur l'onglet qui contient les vignettes speedDial (sinon, aussitôt que l'on accède à cet onglet, une nouvelle fenêtre s'ouvre pour ouvrir le site dans un container alors que l'on n'a pas cliqué pour ouvrir le site).
Donc, si vous avez SpeedDial, il ne faut mettre aucun des liens des vignettes dans un container (en cochant "s'ouvre par défaut dans ce container"), donc très peu d'utilité d'avoir des container...

Revision 2:
Is it really necessary to require the history setting to be "Firefox will remember history"? Why not drop that requirement and use the container idea as part of individual tabs in Firefox? Allow a setting that will "containerize" each individual tab.

Revision 1:
Containers now work after turning setting options/privacy & security/ history to "Firefox will remember history." Review will remain at 1 star - now I have to manually handle history and cookies. I'm not sure containers are worth this inconvenience.

Original Review:
Completely non-functional, counter intuitive, worthless and useless. Total gibberrish for user instructions. NUTS!!!!!!! really wish I could use this - but ........ I'll just have to rely on closing and restarting Firefox after using some google product or facebook.

Es funktioniert bei mir nicht. Ich habe Seiten in Containern gespeichert, die sich dann nicht öffnen, es öffnet sich nur ein neuer Tab mit der Farbkennzeichnung.

Badddd ، why don't sopport android??

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.

Please redesign and remove submenus in this extention. It should be easy to switch between containers. Show or Hide container should be near Kategory not in submenu.
Hide last container should not close firefox entirely. Instead open an new tab. When I close the tab it should not be deleted from container. When I switch container other containers should close. It is not user friendly like it is now.

Nutzlos! Das ist nicht mehr als Lesezeichen auch bieten.

trop complique ttout cela

Containers Add-On won't allow me to set up my work G Mail account. It keeps kicking me back to my personal account. Ridiculous and frustrating.

This is not a replacement for Tab Groups as Firefox suggests, this is archaic and can't do a tenth of it feature-wise.

Sometimes the scripts of certain pages that are contained in one container are used in the pages of another container making some kind of Cross-Sripting and blocking pages such as Wikia.com and many others. Basically it's because most of sites are interrelated.

As well that when a link is opened from inside a contained page that link is contained either and not independently from that domain containing.

And now it just logs out my accounts that were not in a container and later I tried to log in to them in the default container instead, and actually can´t mark to open them always in the default container.

Funktioniert nicht

While the add-on mostly works okay it causes some strange problems. On sites such as pinterest, if I click on a link to open in the same tab, it works fine. If I middle or right-click to open the link in a new tab, the first image or header displays, but the rest of the page is blank with a spinning wheel icon at the bottom, as if it's loading more (which it's not, there is no loading indicator on the tab itself). It does this for every link on every page of pinterest.

With this extension disabled, I get the normal expected behavior: the page is complete on both same and new tabs. I'm only using pinterest as an example, because I know the general layout of the images there. I know when I'm not seeing most of the page. Since I don't know this for most other sites, I don't know what other information on not seeing on those sites when using new tabs with this extension.

Until I know I can open in a new tab without losing information, I won't be using this add-on.

It worked great until all my add-ons got disabled. Because that got rid of all my profiles for this add-on.
