Works well untill you change computer and set up a new browser. The containers are synced in random order an there is no way to sort them in "Open new tab" menu or in about:preferences#containers tab. There is sorting when clicking on a badge but it doesnt affect order in new tab button. So if you want to have same sorting in 3 different browsers you have to delete everything and create containers one by one constantly syncing and checking all devices. Horrible UX.

Muy útil para organizar el tipo de navegación que se quiere hacer: personal, de trabajo o de redes sociales, por ejemplo. Excelente para que los inicios de sesión y "cookies" queden cada uno en su contenedor correspondiente e interaccionen entre ellos por contenedores. Gracias por esta extensión.

Very helpful in managing different logins to same website like I am using another browser for the accounts.

I recommend this plugin who needs multiple accounts login and are carrying out multi-tasking!

Superb, Awesome and thank you to creators of Multi-Container and thanks a lot to Firefox Browser!

Ya no puedo trabajar sin esta maravillosa extensión, para mi su uso es tan natural como respirar.

This extension is awesome, except for the fact that EVERY time you click on a link, open a new tab or type in a website url an error pops up asking "Open this site in your assigned Container?". You are then required to click ok if you want your page to load. The Firefox forum shows several people asking for a solution, with Firefox devs stating there is no solution because "Interrupting the user every time they open a new tab is how the containers plugin is supposed to work." As far as I can see, no one has been able to find a work around yet to make it so that when you right click and "open in new tab", Firefox is actually able to figure out how to open your link in a new tab without popping up that extra prompt.

This is an absolute game-changer.
It is unique to Firefox, and one of the reasons I will never switch to another browser.

Allows containers for different accounts.

Remember to get the "Facebook container" add-on as well!

Five stars!

Super useful

Using this container has made my browsing more private. There is a bug that if I add a new container and re-arrange it, the shortcuts don't change according to the order of containers, the new container always picks up the higher number.

Allows you to maintain separate logins or even separate sessions for the same login. There is one missing piece of functionality however, which is that although you can specify sites to always open in a container, you cannot specify this for individual URLs (e.g. bookmarks).
