So far, working. But please, remove the "Can't see your scan list? Upgrade to Update Scanner 4". Ok, I understood there's a paying upgraded version of this addon, now you can remove it, it's annoying, and its clutters the view in the side panel.

Edit: yes, I have very few item in the list, but it's still distracting.

The update scanning works quickly and efficiently.

Does not work in URL: http://www.nirsoft.net/utils/netresview.html

Needs faster refresh rate.
I use it for internal resources and 5 minutes is way too long sometimes. I would like the minimum to be at least 1 minute, 30 seconds even better.
