Works okay, but now it asks to "monitor extension usage and manage themes" which seems rather out-of-scope.

Schade, dass es keine deutsche Anleitung gibt und man den Text auch nicht kopieren kann um ihn in einem Übersetzungsprogramm zu übersetzen. Abschreben möchte ich den TExt auch nicht.

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!

Bug report!
-------------

After I removed Firefox Multi-Account Containers add-on, the 'Open Link in New Container Tab' context menu item is still working!

I had to create an other Firefox profile without this add-on to rid of it!

It's great to be able to keep my work and home profiles separate, but which links I want to go to what profiles when I open them varies by machine. It doesn't play especially well with firefox sync yet (because the naive way is wrong! Context varies with machine a lot)

Opening new links and choosing a container is a little laborious.

Switching between containers when you choose the wrong one is tough too.

Interesting add-on.
It can be better with the capability to move a tab into another container.

I really like the idea. So far I have only two problem using this add-on: when I open a new container-tab, it will take some time (an unacceptable period of time) before it's ready to work; and this add-on lacks of rich keyboard shortcuts which is something I quite depend on.

Good to have multiple account. Not so good to manage multiple tabs in groups.

Every time I close and open the browser, tabs are reset to some state that was a couple of months ago. It does not restore the tabs and containers that were open when I closed the browser.

This is an excellent plugin but it suffers from not enough administrative interfaces being exposed. To use this addon successfully I'd need an interface where I can manage the auto-open-in-container lists easily and quickly. I've also run into a few problems where auto-open hasn't kicked in, and I've clicked a link and been left wondering why I'm logged out/logged in as a different account. Cheers.
