My ISP is by-passing Firefox's address bar search

My biggest complaint with most DNS servers is webpage forwarding. There's nothing more aggravating than having to type in a really long address -- missing it by a single letter -- and then getting forwarded to an "oops" page, and then having to re-type the entire address all over again from the beginning. It seems that more and more ISPs are now set up this way, as was Open DNS when I tried it.

With the "old" way of getting a 404 error page when a wrong address is typed, I could just look up at the address bar and see what I had just typed, and correct a letter or two. Much, much less work.

Does anyone know of a DNS service that will NOT forward mis-typed addresses?
