Nice, thanks. Maybe add set -e? Had a docker build succeed even though unzip(1) wasn't installed.

Here http://bernaerts.dyndns.org/linux/74-ubuntu/271-ubuntu-firefox-thunderbird-addon-commandline is mozilla-extension-manager script that can automate installing and removing extensions (local or globally) via command line.

Not available now. Some other source?

Thanks!

From my point of view, sideloading and activating addons is not supported anymore. At least I could not find a way. However, what you still can do is, to add an addon to your firefox profile, but you have to manually activate it at first. This bit of automation makes everything at least a bit nicer.
You can use the following script:

#!/bin/sh
# -------------------------------------------------------
#  Command line script to install 
#  Firefox and Thunderbird add-ons
#  as global extensions available to all users
#
#  Must be run with sudo
#  Depends on unzip and wget
#  Parameters :
#    $1 = URL of extension on https://addons.mozilla.org/
#

# -------------------  parameters  ----------------------

# set default add-ons URL base
URL_FIREFOX="https://addons.mozilla.org/firefox/"
URL_THUNDER="https://addons.mozilla.org/thunderbird/"

# set global extensions installation path
# you may have to adapt it to your environment
PATH_FIREFOX="/usr/lib/firefox-addons/extensions"
PATH_THUNDER="/usr/lib/thunderbird-addons/extensions"

# ------------------  Script  --------------------------

# determine if we are dealing with firefox or thunderbird extension
EXT_FIREFOX=`echo "$1" | grep "$URL_FIREFOX"`
EXT_THUNDER=`echo "$1" | grep "$URL_THUNDER"`

# setup global extension path accordingly
if [ "$EXT_FIREFOX" != "" ]; then PATH_EXTENSION=$PATH_FIREFOX
elif [ "$EXT_THUNDER" != "" ]; then PATH_EXTENSION=$PATH_THUNDER
else PATH_EXTENSION=""
fi

# if add-on is recognised, install it
if [ "$PATH_EXTENSION" != "" ]
then
  # download extension
  wget -O addon.xpi "$1"

  ADDON_ID=$(unzip -p addon.xpi manifest.json | grep -Po '"id": "\K[^"]*')
  # to make it a bit more failsafe, you could also use jq:
  # ID=$(unzip -p addon.xpi manifest.json | jq '.browser_specific_settings.gecko.id')
  mv addon.xpi "${PATH_EXTENSION}/${ADDON_ID}.xpi"

  # end message
  echo "Add-on added under $PATH_EXTENSION/$ADDON_ID"
fi

One more hint: To always download the latest xpi from the addon store you can use the following URL:
https://addons.mozilla.org/firefox/downloads/latest/<plugin-name>/latest.xpi

You can identify the plugin name from the URL in the store:
https://addons.mozilla.org/de/firefox/addon/foxyproxy-standard/

E.g .for the foxyproxy plugin you should use "foxyproxy-standard"
https://addons.mozilla.org/firefox/downloads/latest/foxyproxy-standard/latest.xpi
