This is a powerful tool and an instantly essential part maintaining your privacy online. Thank you Mozilla!

You can add Password Pop-up?
For an example:

I open my personal multi-account tab, when i press it
that container requires my password to continue

I love this add on. I think it's particular great if you are in IT or any place where you have multiple access levels in different accounts to the same service.

Good stuff

I love these multi-account containers, and I'm not just using them to force Facebook and other social media sites into specific containers, but also to allow myself multiple simultaneous identities when testing websites, etc.

Muy útil, aunque se requiere algo de disciplina para mantener cada cosa en su lugar.

The main idea is good when I want to logg in for more than one acount on the same site, but...
when I load a site in a container, the first cookie for that site will also remind outside that container. So if I use a cookie autodelete add-on and quit the loaded site in a container, that cookie will still remind in Firefox. Then I have to delete the cookie manually to get rid of it, and THAT IS A VERY VERY BAD IDEA!

For me it's better to load a news site in an ordinary tab so the cookies can be deleted automaticly at a choosen timelaps, and thus preventing cross-links towards that cookie.

Love this tool for privacy, and productivity working between different jobs. But more often than not I find myself going to a site in the wrong container tab, and wish there was way to reload the same tab in a different container. Currently opening a new container tab, copying and pasting across the address across is super clunky.

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
