I have setup Firefox to run off a server for a group of people, so that it runs for them without a local install. Now, I wish to also setup a few extensions globally, which would be available to all users by default - would be great if I could also configure them!

Some desired addons as of now - Firebug, downloadHelper, new tab redirect

Manually download the extension, and then install by running the Firefox binary with the -install-global-extension switch with an argument that is the pathname to the extension.

I tried it, but the extensions still only got installed locally to my profile & were not available to everyone :( – Saurabh Feb 16 '12 at 8:57
