It's good start.

The interface could be improved. It's very clunky to add and manage new sites in containers. You can't add currently opened tab website to a group. You can't manually add or edit websites. You first have to open a new container then load the website then tick "always open in ___" if you want it loaded as default. There's really no options to speak of. You can change the name, colors and icons of containers and that's about it. Opening a link in the same container designated for facebook that embeds facebook trackers kind of defeats the privacy. Making the container exclusive to the specified sites as option could help.

As much as I find this addon useful, it's developed by Mozilla, It's no Screenshot add-on. I imagine it will eventually meet the same fate as Tab Groups.

Me encantó, se tiene un mejor control de acceso a mis diferentes cuentas, solo me gustaría que se pudieran borrar cookies y cache por contenedor, pero fuera de eso es excelente.

Excelente poder separar las cookies, muy útil para evitar rastreo de Google & co. por ejemplo. Muchas aplicaciones.

Ok

good one

Containers have become essential for me, absolutely love this extension.
The only thing missing is support for Firefox Mobile.

Earlier, I would use the Private Browsing feature very often, if I wanted to sign into a different account on a service without signing out of my existing ones. Now, Multi-Account Containers makes it much easier—and I don't even have to re-enter my logins!

Useful for managing multiple sets of logins without having to switch browsers. The "Always open in this container" feature is very helpful: I can make certain websites automatically open in the container I choose. And there's also "Open link in Container Tab" for when I'm clicking on links.

Una muy buena extencion la recomiendo

good

Thank you!.
Is very easy and useful the tabs containers

I use it constantly to keep my personal/work accounts separated and it works great!

I use this extensively, it works great, and keeps me organized and on track.

This is the best thing since Profiler. One of my biggest concern (or dismay) with FF57 is that my Profiler is now a Legacy add-on. Until I found this. And it works perfectly... for now... until they (FF Developers and Community) decides to make changes again. The Internet (and everything) is (are) always changing... :-)

I really love it
