Why is Firefox 25 automatically connecting to Bing and Yahoo on port 80 and Google on port 443, and how do I stop them?

Using Process Hacker from SourceForge, I find that Firefox 25.0.1 is automatically establishing connections to Bing and Yahoo on TCP 80, Google on TCP 443. If I close the connections, they all automatically reconnect. I can't find anything in about:config that would explain this.

Specifically: any.edge.bing.com Port 80 TCP mia05s18-in-f19.1e100.net Port 443 TCP rtr1.l7.search.vip.ac2.yahoo.com Port 80 TCP

How do I prevent these connections from happening?

Thank you.

Try this 

Hi. In Firefox, in the top menu line, go to 'Tools' option.
   Click on 'Options'
   Click on 'General'
   On the line that says about 'Homepage', type in the box,  
    www.google.com
   Then click OK, close Firefox, and restart it. 
 OR

1.Launch Firefox. 2.Type "about:config" in the location bar. 3.Click on the button that reads, "I'll be careful, I promise!" on the screen that warns you about your warranty. 4.Type "keyword.URL" in the filter bar. 5.Right-click on "keyword.URL" in the search results. Click "Reset."

Thank you, but I don't think you understand. Firefox is connecting to servers from Bing, Yahoo and Google the moment it starts up.

I believe I've narrowed it down to nss3.dll, which I have located in My Documents. At 1,735KB it's almost three times as large as any of the versions I can find documented on the web.

Is that the right place for it? What is the right size and location for that file?

Just to be clear, these connections start when Firefox starts up, and do not change at all no matter with changing web pages.

I'm not sure why Firefox would be using a file in My Documents... on my Windows 7 64-bit, the file is that size, but it's in the main Firefox program folder 

C:\Program Files (x86)\Mozilla Firefox

Also, please see this article for any enlightenment it might provide: How to stop Firefox from making automatic connections.
