The prefetch demo is obnoxiously misleading. If it is definitely the link you'll be loading, I doubt you will wait upwards of 7 seconds before clicking the link. In which case, it will not be 0 seconds loading. Then there is the equally likely, you were confident it was what I wanted, but you were wrong case. In which case I just downloaded a ton of garbage I didn't want. (Can't wait for ad servers to preload their assets for you...)
And this is also somewhat amusing, since if I recall firefox has boasted 0 second reloads when you hit "back" fora long time now. Does chrome support that, yet?
The prefetch is an option which you can opt-out from, and i think you are mixing prefetch and prerender, just to let you know Firefox has actually supported prefetching since...wait for it... 2003.
