Link Prefetching, are you pro or against ?
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.
Google support this feature for firefox, and allow to prefetch the first result in google search so you can open it very fastly. But is this a good idea ? Mozilla will open a page in the background for you without you know. And if you didn't want to visit that webpage ? Personaly I have disabled this feature, don't worry it does not prefetch all links.
If you want to disable this feature, type in the location about:config, list of configuration option will be displayed. Type in the Filter area network.prefetch-next, the current value will be true, you can just double click to toggle it to false.
If you want to use this feature on you website, you can read the prefetching hints on mozilla website. It could be useful to prefetch an alternative stylesheet for a website.
