Fonctionne parfaitement.

Very useful for keeping multiple accounts.

Very good at keeping identities separate.
I would find it very useful if the Default Container could be a tab in a Private Window.

To have to open multiple accounts on the same service is an old problem which I usually solve using private mode or multiple browser.

Today, this is one of the most useful Firefox add-ons.

Super helpful for me to deal with work vs personal accounts on the myriad websites that don't support multiple sign-in.

Far better than janky solutions like constantly signing in on a private browsing window, or using a second browser like Edge for certain accounts. Way less time wasted compared to constantly signing out and back into accounts, especially when considering 2fa.

The one thing that feels missing which I wish it had, was some sort of button to switch the container that a tab is in. I'll open a link to a tweet and it'll be in the default tab, in order to put it in a container I have to copy the URL, open a new container tab, and paste it in.

The most innovative add-on I've seen in a long time.

The ability to isolate tabs to containers and use multiple accounts from the same domain in the same browser is really useful.

Also, the privacy factor, stopping FB, Google, and Advertisers from tracking you across the web because the cookies etc. are isolated to each container is simply awesome.

However, for some reason I am unable to save articles to Instapaper using the Instapaper add-on, if someone could let me know how to overcome this issue that would be great. :-)

Best reason for switching to Firefox!

Google Chrome accounts are more straightforward to use, there is no sense in discussing this.
Containers on Firefox are more useful though. They take some use to it, tabs do not sync over (Desktop) devices but enable you to make much more than just accounts. If you take privacy seriously, this is the way to go.

iz gr8t, I found good ｕｓｅ

Previously was very nice but now it sucks

It was better during the Test Pilot. So many features are missing now.

It's out of the box

I think it saves me the time to sort my tabs. The feature where I can open multiple accounts in the same browser is great to test out stuff.

Great for improve your privacy

Super zum Entwickeln!

I can finally use various Google services without then Google following me everywhere. It's nice to have different purpose accounts completely separated. Also love that I can set websites to automatically open in particular containers.

Rempli son office : simple et vraiment très utile, que demander de plus à cette extension si ce n'est plus d'icônes pour plus de variétés ?

L'UX peut encore être améliorée et il y a des fois où c'est légèrement contraignant, mais déjà un outil utile

Great Add-On!
Just sad that it doesn't work on android.
Further suggestion:
1. Better way to modify the container settings
(basically direct access to storage.js with a nice UI)
2. Import/Export (since sync doesn't work)
3. More colors and more icons! :D
