xAuth session cookie in Firefox?

[#1]

Whenever I start FF I'm getting this cookie being set in FF. The IP is always a plusnet one.
Any ideas what it is? It doesn't seem to come from any websites that I have open and it never happened when I used Sky Broadband?
Cheers!
Paul.

It is your IP address and I have no idea why that is happening

Has me flumoxed (sp?) as well.

Do you run your own webserver with php on your computer or network?
As oldjim says, is it your own IP or another? - You can check your IP address here: http://www.whatismyip.com/
If it is, then you have a webserver on your system and something that is calling it (possibly a plugin or virus) and that is causing it to set a session cookie.
If it isn't your ip then for some reason firefox is making outbound contact to that IP address for some reason. Could be a plugin or something sinister.

I said that it is not asking whether it is

It's my IP. I have no servers running on my machine, they are on my server (another Win 7 machine). It had a complete rebuild in the past 2 weeks and was doing it before as well. I run Eset Smart Security. I guess it's possible that it's an add-on but not sure what would do it. The only thought I had was maybe it was the router but it should only do it if the router page is open.
