I want DNS prefetching for Firefox
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.

I think firefox already has this. See about:config under network.prefetch-next and set it there. It may be enabled by default.
Cheers!
network.prefetch-next appears to prefetch the entirety of certain pages, but only “if the webpage hints to the browser that certain pages are likely to be visited” (http://kb.mozillazine.org/Network.prefetch-next)
What we want is just a pure DNS prefetch. Incidentally, another good extension would be a way to add/remove entries from the Firefox DNS cache, effectively like “temporarily editing your hosts file, and just for this browser.” Would love that as a web developer.

There is a new addon for firefox. No idea if it is okay.

Great find Oli – thanks ! I installed it right away.
The initial release is dated 18 September 2008 – just one day after my post… Looks like we have had the same thoughts – and he delivered the plugin !
Here is the link to the page in English (you linked to the German one) : https://addons.mozilla.org/en-US/firefox/addon/8923
is it worth installing if you have fasterfox with enhanced prefetching enabled.
@pete my guess is no because in order to prefetch the content of the next page (as I’m guessing FasterFox does) it inherently needs to do a DNS lookup as part of that. So it would be redundant.
DNS prefetching looks like being default in Firefox 3.1:
