You get the same error page if you try this:
  http://www.google.com/wiki/URL_redirection

Firefox is probably thinking that en.wikipedia.org resolves
at DNS level to the IP of google.

In that case, you will get the google homepage with
  http://en.wikipedia.org

I don't know how it happened. Does it go away if you restart Firefox?
Does your ISP do some authentication using DNS hijacking?
The Firefox DNS cache appears to be polluted.

strange ipv6 effect??? 8-)

A proxy would have likely said "Google error - can't contact
en.wikipedia.org ...".
