How to turn off always open as this?

I like it. Not difficult to learn how to use.Cool concept any other verbs to describe 2 thumbs up.

TODO:
add grouping multiple tabs into one container in the tabbar ;)
Besides that its looks useful

Quite useful add-on and works as expected.

Nice addon, but it does not work with Google Admin (https://admin.google.com/) and Google Photos (https://photos.google.com). After including these in a container with other Google apps , opening them returns a 400 HTTP error.

great idea & a simple way of improving user experience on Firefox but the best feature that can be added is the possibility to group tabs of the same container in the top tab bar

Sans savoir comment évaluer l'efficacité de cette extension, si elle fait ce qu'elle promet, alors j'ens suis très content.

Can we get automatic sorting for the containers? I have a bunch but they're all sorted by the date they were created. Manual sorting is there but it doesn't change the order in the menu where you choose which container to open a site in.

Very helpful for productivity! Grateful for the features of this Add-on.
