Firefox Add-Ons - ASN and IP Info

I have gotten kinda crazy about FireFox add-ons in times past, but nowadays on my new desktops, I have limited what I have installed due to supposed compromising activity with browsers with numerous add ons.

For spamvertized domain research and for sometimes just plain curiosity, I have ASNumber and ShowIP plugins installed. They show up in the bottom right of the browser. When you right-click on the IP info also let you copy and past the IP if you want to find out more using ARIN searches. Once in a while, the ASN won't be associated with an IP, but for the most part this add on is great.
