Windows 7 Professional 64-bit FF 18.0.1
My home page is set to www.yahoo.com When I click on the home icon (or type the same address in the Address bar), the address bar changes to http://www.yahoo.akadns.net/ and the server not found ff built in error page displays I have the live http headers add-on, and there is no actual http request sent.
It's not malware. It's load balancing. AkaDNS.net belongs to Akamai Technologies, one of the world's largest content delivery networks.
However, you should be seeing www.yahoo.com in the address bar, and the site should of course actually load. See the following article:
however the user agent seems of the question's owner seems to be corrupted (not sure if this might be related to some sort of malicious software)...
First of all, "akadns.net" is not malware-related but a domain from Akamai. It is/was used for load balancing services.

The weird thing is that you only experience this issue in Firefox and not in other browsers installed on the same machine. I would suggest you to reset Firefox to make sure that no add-on or config is the culprit: http://mzl.la/MnSTZB
Btw: "yahoo.akadns.net" doesn't load for me too.
But for the Akimai address, it would seem to me that this would require a redirect, i.e. an actual http request being sent?
anyways, very strange that it would just 'rewrite' an address that I manually type in the address bar; perhaps FF 'caches' the redirect? so that it doesn't actually send out an http request? I suppose that's possible
Well, the problem has gone away. Still would like to understand what FF was doing.
and http://www.yahoo.akadns.net/ is no longer a valid domain. but you would think that ff would detect that and invalidate its cache
ps: btw, i did startup ff in safe mode, so it wasn't any add-ons
Well, "madperson" is right, your user agent is weird. In fact it's quite uniqe with that "nomagic bot" included (at least Google says so).
Afaik the default one for you should be: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:18.0) Gecko/20100101 Firefox/18.0
So better search for malware I would say...
Nah, that's a custom user-agent string I defined for my own purposes.
BTW, how/where did you see that user-agent string? not sure where google fits in (perhaps it was automatically added to the initial support request, but don't see it on this page)
