Perfect and very helpful! Mozilla is amazing!

settings is not synchronized

Best extension !

Should be embedded by default with some ui refinement maybe...

Muy bueno lo esperaba hace rato. Gracias equipo de Mozilla sigan así que es el mejor navegador!

Ajuda muito na organização de abas, sem a necessidade de abrir janela anônima. No entanto, senti falta da possibilidade de "jogar" uma aba já aberta fora dos containers para algum deles. Mesma coisa sobre mudar o container que uma aba está. Espero ver esse tipo de função no futuro!

Nutzlos! Das ist nicht mehr als Lesezeichen auch bieten.

Это расширение мечты! Сколько лет мы держали несколько браузеров, чтобы не входить/выходить в разные сервисы десятки раз в течение одного дня и вот оно — настоящее удобство! Где же вы были столько лет? Эта идея, казалось, лежала на поверхности… Спасибо!

SIgning in and out of ''multiple'' Gmail accounts. Makes it a breeze now, I love it! Thanks.

Useful tool to launch web-applications that allow one concurrent session only.

justo la herramienta que necesitaba para manejar todas mi cuestas en redes sociales

excellent

Really cool idea!!
Some ideas, how about different bookmarks for each container, so I just have the appropriate ones visible

Please, add option "Open all tabs in this window as - ..." - for example I want to open two Firefox windows, first for my own workspace, second - for work. And I want all tabs belonging to these windows follow same behavior.

Great addon, thank you!

Great idea! Thanks a lot :)

Great - used different versions of FF via profile parameter before, this seems to be a much, lighter, better solution.

Suggestion: Can you move the color-marker to the top of the tabs? The "here is something new"-indicator icon collides with the group color markers.

Containers should have separate histories, sync over devices and support android. People use different identities online and their history/bookmarks should be split too.
