Background

DNS prefetching was implemented in Firefox 3.5 to improve page load time. This feature allows Firefox to perform domain name resolution proactively and in parallel for hyperlinks, images, CSS, JavaScript, and other webpage content. [1] [2] Note: To disable DNS prefetching using about:config you will need to add network.dns.disablePrefetch as a new boolean preference and set the value to true.
