I just realized that Chrome does DNS prefectching and I would like to have that in a Firefox plugin. On fast links and older versions of Firefox, I used to enjoy Fasterfox – a plugin that among other speed optimizations prefetches link targets. Of course, that is a network intensive process that may not be suitable for general consumption. But proactive DNS resolving is a pretty harmless tweak that I would settle for – and the Fasterfox precedent shows that it is quite doable. Of course the paranoid prudent among us won’t like it, but that segment of the population knows how to turn off that sort of feature.
