Here's supplementary information:

Firefox makes unrequested connections

Some people are particularly concerned about the connections Firefox makes to the internet, especially when such connections are made with no apparent cause. This article will explain the various reasons why Firefox may legitimately make a connection to the internet, and how you can stop it from doing so if you so desire.

And one, in particular, that seems a bit too helpful ... might visit!:
What is link prefetching?

Link prefetching is a browser mechanism, which utilizes browser idle time to download or prefetch documents that the user might visit in the near future. A web page provides a set of prefetching hints to the browser, and after the browser is finished loading the page, it begins silently prefetching specified documents and stores them in its cache. When the user visits one of the prefetched documents, it can be served up quickly out of the browser's cache.

And from the last link, there's this:
What about folks who pay-per-byte for network bandwidth?

Basically, there are two ways of looking at this issue: websites can already cause things to be silently downloaded using JS/DOM hacks. prefetching is a browser feature; users should be able to disable it easily.

It is important that websites adopt <link> tag based prefetching instead of trying to roll-in silent downloading using various JS/DOM hacks. The <link> tag gives the browser the ability to know what sites are up to, and we can use this information to better prioritize document prefetching. The user preference to disable <link> tag prefetching may simply encourage websites to stick with JS/DOM hacks, and that would not be good for users. This is one reason why prefetching is enabled by default.
Something more to learn how to control: JS/DOM hacks!!!
