How to use a prediction service to load pages more quickly?

You want to know how to use a prediction service to load pages more quickly, you must understand that there is no code execution vulnerability. Put simply, the bottleneck for any well designed site is the network, so prefetching the data for links reduces the impact that network performance has on actually accessing those links. In essence, what these services do is preload the data into the browser's cache so that you don't have to download it over the network when you follow the link. This is fundamentally no different from manually downloading a copy of a web page using a tool like cURL or wget, no rendering work is being done, and no javascript is being processed.

• There are, however, a couple of other risks with this:
  
• From an outside perspective, without proper correlation, this looks like you're actually following all those links.
  
• Your external IP address gets leaked to any systems you happen to connect to.
  
• Your bandwidth utilisation will look different from how it otherwise would.
  

The first is not likely to be a serious issue unless you are living under a totalitarian regime or frequent shady (but not necessarily illegal) sites. The second is not likely to be an issue (if you are using IPv4, you're almost certainly behind at least one NAT router anyway, and even if you aren't or are using IPv6, there is almost certainly still a firewall between you and the internet). The third is not likely to be an issue at all, but may affect how your ISP handles your connection.
