Video DownloadHelper Addon and jlesage Firefox Docker

[Verwundert]

I wanted to use Video Download Helper Addon (https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/) and found out that I need to install a part via SSH in Linux.
The installation doesn’t work in Docker CLI, and it says ‘Command not found.’ Does anyone have any ideas?
apk add curl
apk add bash
apk add file
