-1 Stars: Can't add hosts/domains manually. This limits the usefulness of this extension considerably, as almost every site redirects from one domain to another, especially for authentication. Please allow me to arbitrarily add domains to the list. It would also be nice if I could have an "add all domains accessed in this tab session to the list for this container" option, to capture any domains redirected to automatically, but manual addition would at least be sufficient.

Pro-tip for anyone else bothered by this: in about:config, set network.http.redirection-limit to 0, and it will stop all redirection temporarily to allow you to add arbirary redirecting domains to this extension. Be sure to set it back to 20 or whatever afterwards.

-0.5 Stars: Can't skip the tutorial when installing the extension. I understand the desire for the intro if you're new, but its clear that the lack of a skip is so that extra products can be cross-sold. Please add a skip option for this.

ichbin firefox zufriden

It works well for nearly 3 years. I am using portable firefox with multi-ac containers for nears 3 years, I have 10 containers, those of them have different user agent, but suddently, since yesterday, all containers share the same user agent and cannot set different user agents for each container alternately.

Could not do my job without this plugin. Absolutely awesome!

Muy útil cuando se tienen cuentas de trabajo y personal en el mismo proveedor y hay restricciones de un lado u otro

very useful extension, keep up with the good work

Multi Account Containers works great for me. I use all the time and have almost 20 containers. Note: I am NOT a bot!!!

good app

Funciona muy bien, tengo correos de diferentes tenants de 365 abiertos al mismo tiempo y sin conflicto.
