Is -install-global-extension still valid or has it been deprecated ?

Firefox 4 no longer extracts XPIs when installing extensions. It just places the XPI file in the user profile, and then reads the chrome files and others directly out of the XPI.

If your .xpi is not from Mozilla addons I guess we may not be sure what it is intended to do, or what version of Firefox it was designed for.

Note that you need to rename the extension and change the file part to the ID of the extension (GUID or email) as can be found in the install.rdf file in the XPI file if you drop the extension in an extensions folder.
