Containers have become an essential part of my workflow for managing multiple accounts, improving privacy, and isolating contexts like work/home life in the same browser. Admittedly, containers will probably never be a perfect solution (e.g. I still don't have a way to ensure that my Google drive link from the electron Slack app opens in the right container for the right Google account)... but Multi-Account containers extension smooths out most of the rough spots by enabling some sites to always stay in a container, and adding convenient keyboard commands and context menu options to open sites in a specific container. It doesn't seem like this extension provides a shortcut for "new tab in the same container", but I'd like to see that added. For now, I have installed another extension that sets that feature to Alt + C. Great extension;, though! I'd love to see it on android.

Great Work!

muy bueno

Helps me organize my tabs.

It's what I was looking for since a long time.
It works great and increase the flexibility of Firefox in a great way.
Now I can have multiple accounts for the same website all opened using my favorite browser.
That's great for work, where I need, for example, two separate logins for Dropbox.
Thus far, it worked great.
The only function I'd like to be developed, is the possibility of 'converting' one opened container into another... but I believe it's not straightforward, since one of the feature is to grant isolation between them...

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!
