Awesome tool! Prevents confusion when using services with multiple IDs.

An absolute must have.
It allows in the same time to reduce our privacy exposure and ease the use of multiple accounts on the same domain.

An exemple of usage I love is connect to gmail with an account and to youtube musique with another account because it have subscription to it.

PS FOR THE DEVELOPPERS: The only missing feature for this extension is the ability to isolate plugins too.

It is very useful addon! I really love it!

This should be rolled out as a general feature. Some services or segments are just part of our lives, but are too intensive and invasive. Firefox containers is the best solution/workaround to these 'necessary evils'.

Precisava acessar usando diferentes perfis, para isso ou tinha que criar personas ou iniciar o navegador com diferentes pastas de usuários para ter configurações distintas.

O Multi-Account-Containers permite eu manter tudo em uma só instância do Firefox, o que me salva muito processamento e memória, podendo abrir vários perfis da mesma rede social ou do mesmo serviço de email agilizando muito o trabalho.

Fui além, e descobri a possibilidade de melhorar a privacidade abrindo sites "pais" de muitos rastreadores apenas em um contêiner específico e deixando literalmente as bestas presas em suas gaiolas.

Firefox inovou muito com esse recurso, sem dúvida deveria se tornar padrão (inclusive mobile).

I use Google for work and home, and Containers is the only way I can avoid repeated login prompts and Google services that insist on using the wrong credentials. It's a unique feature that keeps me coming back to Firefox!

Multi-Account Containers makes my life with multiple clients and many identities much easier. Great add-on if you have more "contexts" in your online life and you want to keep them separated.

I have multiple clients for my business with many overlapping web services which I need to log into with multiple accounts simultaneously. This add-on is perfect for my needs and solves a real problem for me.

Very good. The only one more feature I need is ability to set home page for container. I use some containers only for e-mail accounts or other one specific site and I'd like to have open this site automatically when I open container.

Really good. Really help me to check my accounts as if I wasn't logged in. Also it can help me to separate work and daily life browsing.

Great add-on, I use it for personal/work separation, banking, shopping vs. social media separation.
Works great, allow sync between devices, remember site>tab assignment

For IT - great when working with multiple identities in same services like o365

It would be ideal to be able to clean private data from containers. I love the option to clear browser data when closing it, but it would be very useful to be able to clean the containers in a particular way (or if there was one that was automatically cleaned when closing Firefox).
