Firefox - Multiple users, same extensions

[Yenji]

By any chance does anyone know of a way to allow firefox extensions to carry over between multiple user accounts?

Basically my family computer has three different user accounts on it. Instead of installing the extensions on each account I would rather just install them once with everyone having access to them

Global installation

A global installation will install an extension to the application directory rather than within a profile, so it will be available to all users. To perform a global installation you should not activate the .xpi installer file within your Mozilla application. Instead, download and save it to disk and ensure that you close the application completely. Then restart it with the following command line arguments:

-install-global-extension "<path-to-extension>\extname.xpi"

where "extname.xpi" is the name of the installer file.

Depending on the extension, each user may need to configure a globally-installed extension independently.
would be the best bet

That did exactly what I wanted. Thank you very much :)
