So, if you want to open some websites always in isolated containers of your choice, then this tutorial is gonna help you.

To automatically open websites in isolated containers in Firefox, I am using a free add-on named “Containerise“. It provides 4 different containers: Work, Shopping, Personal, and Banking. Each container also comes with a different color to easily identify it. You can add website of your choice to any of those containers. After that, whenever you will launch that website or associated webpages, it will open it in the specified container automatically.
