Made absolutely no difference. It was a sham! Also it was so odd to force users go change about:config settings. Should they go and manually reverse those changes after removing this crappy add on?

It could be somewhat useful if it detects the next page on consecutive pages and preload that but it doesn't!

Poorly created extension. We should never have to go manually visit about:config to enable an extension. Moreover, it doesn't do anything. There are privacy implications when messing with prefetching dns. Not recommended.

En muchas paginas las carga con error, y aun siguiendo el procedimiento que indica, no hay mucha diferencia a como carga normalmente firefox. Una chachara.
