I'm completely satisfied with this extension. It allows to keep multiple sessions (i.e. session cookies) to the same website thus allowing multiple logins. As a developer I use this for verifying the functionality of webapps that have multiple roles. Thus extension fully replaces SessionBox that was available on Chrome and now no longer works. Thank you.

Simple, intuitive, works seamlessly. My main use case is to isolate IBM product administration consoles.

Separating FB from Instagram is tricky (Have the Facebook container extension too, that comes default with FF). Since it wants to always open those websites in the container. Managed to separate them the first time but somehow it kept erasing the Instagram session at every restart of the browser, didn't know how to restore that so had to nuke the container and start over.

Mis alleen het stapelen van containertabbladen.

comodissimo
per me indispensabile, avendo tanti account diversi da gestire

I have 2 profile, cannot open gmail from profile 2 when it redirect immediately to google account on profile 1, No feature to disable that situation

Me sirve muchísimo cuando tengo que administrar varios sitios web al mismo tiempo, administrar varias cuentas de WhatsApp Business para mis negocios o cuando tengo que estudiar e iniciar sesión en una sola página al mismo tiempo, mil gracias por tan valiosa extensión, busqué algo similar en otros navegadores, pero Firefox es superior en todo. ¡Mi más sincero agradecimiento a los desarrolladores de esta extensión! (:

Говно. Сосите у хохлов, пидоры.

They separate single account with multi categories, not multi accounts. They claim that categories exist, but the way to open them is difficult – click here, then here, and choose from there. They may have ideas for the future, but for now, this is my review. Best wishes

A good idea but completely unfinished.

Sync to a new browser always merges the default configuration without asking. The Sync does not sync the 'limit to designated sites' option, so you have to manually apply that to all the categories (while you clean out the merged in default configuration).

Management of the categories is woefully sub-par; how is there no way to manually add domains or wildcard domains to a category? Try keeping a service like Google in a 'limited' category and watch the SSO explode every time you go to maps dot google dot com because the browser doesn't stay on the auth redirect long enough to add it to the container though the UI.

It also breaks the firefox profiler, as the profiler can't load profiles from outside the category.

None of this bothered me when this feature was new, but it's been years. I wish I could recommend this and use it in earnest.

Offers to sync with android, but the extension is not available for android (doesn't appear in search results) therefore impossible to sync with multi account containers on Pixel 7a. Don't know how this will work with multi account containers on my laptop not syncing with my phone
