This extension is excellent if you own multiple accounts for the same service and want to keep things isolated.

For instance, I have a personal GMail account and a work-only GMail account. It's nice to keep these things separate, because then you can use Single-Sign-On authentication without needing to continuously specify which email account I want to use for signing.

You can also associate certain websites with different containers, so that they are always opened in the appropriate container. Very useful as well, though it can lead to problems when you open the same website in two different containers (for example: I use GMail for both work and personal matters).

My firefox is updated but still unable to add this extension.

Sehr nützlich um privates von Geschäftlichem oder Entwicklung von Produktion zu trennen.

Bonjour,
I see in grayscale, so your selected color have the same luminance infos, I can't distinct any colors.
Can you add a color picker with no default color but all the color spectum?

Bien à vous!

Hi,
parceque je vois en noir et blanc les je ne peux pas distinguer vos couleurs, car elles ont la même luminance.
Serai-il possible d'ajouter un sélecteur de couleur, sans couleur par défaut mais un spectre complet, pour un réglage fin?

Best.

This is one of many reasons Firefox will always win over Chromium-based browsers.

There's a few problems that continue to persist even after many years however:

1. Stop trying to shove Mozilla VPN down our throat.
2. Sync tells you to sign in despite already being so - just close the extension window and re-open when it gets to that point.
3. Once sync is enabled, it'll pull through all your containers, but it won't remove the default ones. Very annoying.

Cet add-on indispensable n'est plus maintenu depuis 1 an et est bugué. Par exemple, je dois sans arrêt retirer des sites de la liste des sites gérés par un conteneur car ils reviennent toujours. Ça rend l'identification problématique si un IDP (comme Facebook login ou Google login) se trouve réassocié sans arrêt à un conteneur.

This essential add-on is unmaintained for one year has some anoying bugs. For instance, I'm forced to remove the same website from a container managed website list again an again because it get reassociated again and again.
This cause IDP (like Facebook login or Google login) to fail everytime if their website is reassociated with a specific container. (SSO breaker)

One of the best extentions

Despite having the "Select a container for each new tab" box checked When you open a new tab, nothing happens. Not even contextual dialogue is activated. I have the extension installed and enabled, but I can't get it to work in Windows 10, not so in Linux Mint, which goes without problems.
