useful add-on although it takes up too much space on the toolbar Rated 4 out of 5 stars

This can help you see whether you're on the site you think you are by showing its country, organization, city, etc.

+ can show lots of useful info about this site at once
+ fast lookup (from NY, US anyway)
+ can drag it off the add-on bar onto another toolbar
- can't hide the big labels like "Country Name: " which take up way too much room on toolbar
- the info not being shown can't be viewed "on demand" (hover or click)
- doesn't show the "real" (reverse dns or canonical?) hostname of the site like the WorldIP or ShowIP add-ons.

This add-on is in my Collection "recommended security & privacy add-ons that are minimally-invasive" addons.mozilla.org/firefox/collections/dabruro/security
