This app is great. I use it every day to stay logged into both my work and personal accounts at the same time.

Excellent addon.
But doesn't work since Firefox 89.

Great just misses context button to open current window in another container

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.

I think that this add-on has a lot going for it but it could use some help like when opening a new tab it had the option but currently when working if I want another tab I get thrown out of a flow having to go and click on it on the other side of the browser or use keyboard short cuts but the period is still on the other side of the keyboard.

Love it. Using it extensively for multiple containers.
Only issue is that it does not support syncing containers across multiple machines. My other plugins get synced but not this one
4 stars due to the sync issue, otherwise 5 start

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.

The idea behind this add-on is very good and the current implementation looks promising. It should be integrated in Firefox and made even more capable and user friendly.

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.

There was a huge need for such and addon and it's great to see Mozilla step up to create it. Way more stable than most add-ons out there and extremely useful.

However, matching new sites with containers should be easier.

Looking forward to more improvements, hopefully, in the future.

Una muy buena extencion la recomiendo

good
