How to install extension in firefox automatically?

Hi

I have the need to be able to install an extension that I made myself for Firefox in ubuntu but without a graphic terminal so I need to be able to install the extension without the need for user interaction

I want to do this because I am working with dockers and I do not have a graphical interface to be able to interact with my container that has the Ubuntu system image. And therefore I cannot use beyond commands to interact with ubuntu in my docker container.

try to use the Firefox command:

firefox -install-global-extension /path/to/extension

But it also requires user interaction so that it can accept the installation of the extension.

I found this post but I do not understand how to make the installation automatic because loading the .xpi to the folder with the extensions does not install in Firefox
