Firefox extensions are installed locally into the user home directory and as such, do not require elevated privileged to be installed. Firefox does have a degree of security and extensions cannot automatically be installed without some interaction from the user.

Since the extensions are installed locally, they cannot compromise your operating system in the same way that Windows malware does, since they only have access to /home/$USER and not your entire system.
