After applying cure, why does Firefox still, stubbornly, make unrequested connections?

Question

After meticulous care to follow the guides on the support link titled "Firefox makes unrequested connections" [... http://support.mozilla.com/en-US/kb/Firefox+makes+unrequested+connections?s=firefox+is+seeking+unrequested+website&as=s ...], Firefox is still trying to contact obscure sights like:
iy-in-f104.1e100.net<br>
yw-in-f121.1e100.net<br>
iy-in-f103.1e100.net<br>
The above resolve to google. Yet I am not going to google and do not use the default search provided by Mozilla or Firefox browser. <b>What is causing this browser to go to google, even after I thought I had, several times, performed the cure to stop it from accessing un-requested websites in the back-ground?</b>
Firefox is acting mischievously, because it does this without being told to do that, and after I have asked it to stop. When it does go, it does not post any information on my browser telling me what it is doing.
After much effort to get it to stop, I consider this to be a nuisance that it is stubborn and acts on a hidden code to defeat my requests and actions trying to prevent it. This is the same behavior as malware and viruses that dial back to a location, do not announce what it is doing, and will not stop, after many hours of effort trying to instruct (reverse coding to get) it to stop.
I have now spent about 5-6 hours trying to figure what is the cause, and as such, it can be categorized as time wasted as when dealing with malware, that does not inform the end user what it is going to do prior to installation nor announce it, as it is being done, in the background.
Sometimes Firefox performs a hiccup and tries to change my update settings back to a condition of seeking to update itself or update its addons or updates its search (all options under the updates tab). Furthermore, Firefox has acted on routine of once or twice a month to change from "asking me what I want to do with updates," to "install automatically." Many times in the last 6 months I have seen it was trying to executive a program of updating, when it was not authorized to do such a thing, and was there to cancel this execution-sequence, if not too late. In this 6 to 7 instances, I have been prompted to go back and observe if Firefox is changing my settings by executing hidden code or back door code. In each instance all my update settings have been changed.
I have to go back inside the browser options, and deselect all the updates and also change from "install automatically" to "ask me what I want to do." This is even more curious because, such items were set to "false" via about:config as per instructions in the support link above. Have double checked addons, to make sure they are not trying to update.
In conclusion, this is obviously not a bug, as it is so deliberate and happens on some routine. It seems to a happen irregardless of what "version" or update is being used; including many updated versions since Jan 2010. Also what ever it is, an execution of code or backdoor to trigger same, it is not described in the readme file that comes with firefox.
So how about the programmers of Firefox stop belittling us by employing the same gimmicks as malware and tell us what is up with this: seeking unrequested websites and not announcing that it is occurring, when it is occurring.
