Incredibly useful !! A must-try

Edit: I've removed one point and added a new one.

This should be excellent, but in reality a few bugs make for a frustrating experience.

The containerization really helps when working with multiple contracts for multiple work accounts, allowing several Office 365 sessions to be signed it at a time.

I love the facebook container, as I use facebook once in a blue moon, and love that this keeps it in it's own tiny bubble.

There is some inconsistency though:
1. By default firefox opens with no default container. This means you have to open a new tab in the correct container, before you start browsing, then close the original tab.
2. If you use the keybord shortcut to open a container, it does not prompt you to choose a container, it opens an uncontainerized tab, forcing you to either reopen the tab in the correct container, or use the + in the bar, which is significantly slower from a workflow point of view.
3. You cannot set home pages per container. By default, my "work" container (for my company) always accesses the same site, with all tools launched through that site. If i could set that as the home page for my work container, then it would save me a dozen clicks and keyboard presses 30-40 times a day. Add that time up.
4. You cannot assign a book marked site to a container, as above this would vastly improve matters. THis would make the Top sites useful, as clicking them would immediately take you to the site in the correct container, likewise would mean technical research would be faster as you would not have to open the correct container by clicking the +, then choosing the container, then selecting the bookmark.
5. Turn off the No Container option. Now I'm using containers, all my workflow fits into one of the configured containers, so the no container option is obsolete.
6. Make the option to Sort tabs by container a permanent setting, rather than a one off setting. I end up using this option several times a day to regroup related sites running in the same container together for organisation, but it's frustrating that as soon as I open a new tab of that container it doesn't group this with the other tabs open.

Makes full use of the Container function by automatically opening websites in their appropriate containers.

The extension is interesting, but there is a big access problem with Sharepoint. When Sharepoint is in a container, I can't click on a link toward Sharepoint, the access is denied.

"Keep parts of your life separated".

History isn't separated.

I really like this add-on, I use it every time I browse now and will continue to use it to separate my browsing objectives and information.

The ability to sort and color-code tabs is really great, it helps me keep my computer and browser organized.

A couple things that I feel would really improve the experience for me are:
-the ability to set which container tab Firefox opens in. Sometimes I don't realize I am not using a container when I have been browsing for a few minutes.
-as an earlier review mentioned, the ability to assign websites to containers en masse. This would be much easier than having to visit the site in the correct container and checking the "Always open in..." box.

Once those two recommendations are added, this becomes a five-star review from me! Works great, simple to use, and easy to understand layout. Awesome extension!

Really solid start, but needs a bulk editor so I can set rules up en masse.

My company is using (very) intensively this add-on... Using containers / identity for each client (and we have a lot of clients) permits us to open Office 365 and other accounts many times for many clients at the same time without having to re-authenticate... This is just fantastic.

Maravillosa herramienta, gracias Mozilla!

¿Por qué no integran "Facebook Container" dentro de este complemento "Multi-Account Containers"?

Son complementos muy relacionados, harían más fácil de utilizar el complemento y para usuarios menos experimentados, evitarían la configuración que implica usar ambos complementos a la vez.
