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'.

De oplossing om aan te melden bij verschillende e-mailboxen van dezelfde provider. Bespaart een hoop ergernis en maakt het super simpel zonder iedere keer af te melden bij schakelen naar een ander e-mail account.

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.

Lacks essential features like container content management and many basic quality of life features.
Quickly becomes cumbersome to use, can't set wildcards, causing tons of cross-container switching in regular use.
Having to confirm new container choice on first connection is just a waste of time.
The frequency of updates is very low despite this being a great potential addition/replacement to full browser profiles.

perfect

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).

The only major thing that could be better, is having the tabs group together like in chrome.

Excellent for keeping accounts separate and from sites tracking you across the web. 2 small caveats: reordering containers doesn't seem to work under the "+" dropdown menu, and syncing to another FF instance doesn't migrate your custom containers. Not looking forward to setting up the additional 27 containers I use in each instance - and I use many...
