bash script to export an addon/extension's url uuid given its (partial) name

firefox_extension.sh

function firefox_extension() {
    # Usage: firefox_extension "name" ["url|uuid"]
    # Parameters:
    #     extension_name (string): The name of the addon (case insensitive, could be partial, via grep).
    #     parameter_type (string): The type of information to retrieve (url, uuid).
    # Examples:
    #     firefox_extension "Bitwarden - Free Password Manager" "uuid"
    #     firefox_extension (Lists all available extension names)
    # Notes:
    #     extensions.json has name, url, id
    #     prefs.js has id:uuid at extensions.webextensions.uuids
    #     hard-coded for Mac, but could be modified for Linux
    #     will create output files in extensions subfolder of working directory
