How can I make Firefox use addons for multiple profiles?

How can I make Firefox use addons for multiple profiles? I created a new profile on firefox for testing reasons. I notice no addons except Skype is on it.

"Basically you need to download the .xpi for the extension you want to install. Then run the following command:

\path\to\firefox -install-global-extension \path\to\extension.xpi

I don't know if you can make already installed extensions global after they are installed. Perhaps a combination of this approach with @ChrisF's answer would solve that problem."
