1. BaseOS and docker container are two different devices. So i cant use my baseos firefox on docker container.

2. Docker works on terminal.

3. My BaseOS has firefox.

4. My BaseOS is just helping docker to open GUI apps.

5. By xauth and X11 program its giving a way to open GUI.

6. Lets imagine there are two VMs but they have there own software both can't use each others software.

7. Docker container is a new device which don't have Firefox so to run Firefox we first need to install it and then only xauth and X11 can do there work.
