I just simply love this add-on.

Works great. Easy to set up as you browse normally.

Awesome! What I am missing: I would love to get an option to automatically open in the container based on the URL or match (i.e. https://github.com/Organisation/*). It also would be good if it could open containers and new containers tabs in dedicated window - I usually sort them by topic I am working on

please integrate it with bookmarks so a bookmark can be tied to a container. that would increase the functionality so much.

Wonderful! Only reason I am still using firefox other than better memory management than Chromium based browsers.

Containers are by far one of Firefox's best features. They're easy to use, reduces hassle, protects against Facebook tracking and helps organise tabs for website with multiple logins.
