I used https://github.com/jlesage/docker-firefox in the Firefox cell. His Docker image is pretty good. So, create your favorite cell from https://github.com/jlesage repository. I have already created a working cell on how to use Udocker in Colab. You can learn from it and use that cell to create a new one and share it in the OneClickRun notebook.
