Great, does exactly what it says

Combined with caching, my wordpress pages load instantly now. When I load the network inspector, I see the browser is downloading all visible links during idle time. Very happy, thanks for this addon!

It’s also intelligent loading only my wordpress pages in advance, ignoring all offsite links. I’m grateful for this.

Keep in mind, firefox and safari don’t support preloading yet. You’ll only see this benefits in chrome, for now. This isn’t the fault of the developer, just a matter of support for the browsers.
