Excelente!!!

Must-have add-on if you are in the very least privacy-conscious.

Super

Super add-on or keeping your privacy. It helps you compartmentalize the information you 'share' with the online spies who follow you around. Open a container, go to a site, click "always open in " in the add-on's menu, and every time you go to that site only the work done in that container is available to the site.

veeeery good plugin for ordering tabs <333333

Works great.

Overall I think this is a great add-on. The one thing I wish it had was settings interface where you could manage what sites open in what tabs. If it had that this would be a 5.

Before having Multi-Account Container I was using different browsers to use my email accounts like gmail.com, hotmail.com & etc. and their respective depending social media network sites & business/work sites. Now, I say good bye to other browser.
Additional Features to be included:
1. Firefox Account Synced
2. In-built mail notifier for different containers

I'd give you the fifth star if containers could be synced between different computers.

Love it!

I like it

Очень полезная функция для одновременного использования сайтов под разными логинами! Сильно выручает, когда ты ведёшь сразу несколько проектов.

Works perfectly.
It allows me to work with multiple accounts from the same window, with a smooth workflow.

Después de largos años esperando a esta funcionalidad en algún navegador y sortear su falta usando varios navegadores o programas tipo Electron y similares... ¡Por fin! podemos tener varias identidades abiertas en un mismo navegador sin que se peguen entre ellas. ¡Aleluya!

Encapsulation for containers!

This is an awesome plug-in for developers or anyone that works on the same webapp with multiple user accounts.

As someone who is worried about websites spying on my activity, I love this add-on. It will be even more awesome if the ability to Sync the containers is added.

This is such an awesome feature. I don't know how I ever got along with it. It is great for keeping different aspects of your online lives separate.

Especially worth its weight in gold by allowing you to keep your online banking transactions completely separate from everything else for an added layer of security.

Very useful, nicely separates different web activities. Only missing is synchronization via Firefox account.
