How to remaster Firefox with our extension installed?

[Saravanan.RHCE]

I am designing a Linux distro with Firefox running successfully.

I need to install an extension xyz, so that once my Linux OS boots up
an when i click on Firefox, it must have the extension xyz installed.

I tried installing the extension by command line by adding the
following commands in startup script after X gets loaded.

firefox -install-global-extension xyz.xpi
firefox &

This did not work for me.

SO how to have firefox with xyz extension already installed?
ie what are the necessary files to be placed under extensions
directory under firefox installed directory?

Please help

There are system directories where you can install extensions for use by all
users, they're documented here:
