Firefox.exe cmd support for firefox v20-24 .xpi install

BryanJBowen

Firefox v20-v24 support for "Firefox.exe -install-global-extension "folder\Addon.xpi"" hasn't work since v19 with the above cmd. Is there a new syntactic to .xpi via command line. Also I don't remember there being any help menu Firefox.exe /? If there isn't a command to add .xpi is there some folders/files that could be back & replaced after new firefox install to add .xpi
