I really like the additional security provided by this add-on. The ability to easily handle multiple logins to the same website is also really useful.

I can no longer live without this.

I love this addon. It makes it so much easier to handle multiple sessions with different accounts on the same website. I have not been impressed with many of the decisions made by the Mozilla/Firefox team in quite some time but this add-on is definitely an exception to that. Great add-on!

Ich liebe es. Nicht nur, um Webseiten-Gruppen voneinander zu trennen, sondern auch für mehrere Accounts mega hilfreich. Schön einen Container mit geteiltem Prime Video Account und einen für die eigenen Bestellungen.
Möchte ich nicht mehr missen.

So great for keeping multiple accounts with the same service separate, without having to open a different web browser.

Also good for web developers who have to use the same app in different environments and not have cookies from env A get in the way of env B 👍

Awesome addon, adds a ton of functionality to Firefox, however I wish there was an option to have all tabs in a given window to automatically open to a set container.
In addition, I would love if there were options to have custom colors and custom icons for created containers.
