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

I think you forgot a step. According to:

http://kb.mozillazine.org/Installing_extensions#Global_installation

after the step you did above, then do:

Copy the .xpi file into the <installation directory>\extensions
folder. When you start your Mozilla application again, it displays an
installation dialog, asking "The following items were found in your
Extensions folder. Do you want to install them?"

The site may be out of date, however.
