Get Mozilla Firefox
They recently installed a Rocket.Chat server at my office, which is a chat software solution. Since I didn't want to install it directly on my computer and had never tried Docker, I decided to put it in a container.

Let's see what to do if we want to launch firefox and rocket.chat applications in the same container.
