Anyone used the shodan plugin for firefox or chrome? Security issues?

[stan]

Hi,
I just read a news article, 
http://www.abc15.com/news/national/cyber-alert-hundreds-of-thousands-of-unsecure-cameras-streaming-live-on-the-internet
about a service called shodan,
https://www.shodan.io
that searches for web connected devices, and indicates whether 
they are unprotected or not.

The article gave examples of webcams and devices that are connected to
the web, and wide open.  A quick search for webcam showed many.  There
was the offer to install a firefox plugin. I'm leary; a web site
offering lists of access to unsecured devices wants to install
something on my computer.

Has anyone had experience with this, or any information on whether it
is a security risk or not?

I doubt anyone on this list is exposed, but this could be considered a
heads up to secure any devices attached to the web.  It noted that many
devices are left with the default password only, and that default
passwords are available on the web.  For example, a guy demonstrated how
he could adjust his insulin pump via the web by hacking it.
