mozilla 1.2 is out, and support link prefetching, which is interesting. i really wish it didn't prefetch next links, though. that will just beat up on sites that have gone to the trouble to define next and previous links for areas that may not even be normally navigated sequentially. (like the mysql documentation, for example. disclaimer: i work for mysql ab.)

the query-string thing is just a gross hack that glosses over the fact that the right balance between improving the user experience and not putting an undue burden on publishers was not struck.
