Bug#617881: doesn't Iceweasel cache IP addresses?

[jidanni at jidanni.org]

Package: iceweasel
Version: 4.0~rc1-1
Severity: wishlist

You know often when we've been interacting with a site for several
minutes, we still see "looking up..." as if Iceweasel has forgotten the
IP adddress it has just been using. Then even some:

Server not found

          Iceweasel can't find the server at ragii.com.

  Check the address for typing errors such as
    ww.example.com instead of
    www.example.com
  If you are unable to load any pages, check your computer's network
    connection.
  If your computer or network is protected by a firewall or proxy, make sure
    that Iceweasel is permitted to access the Web.

Which are totally wrong suggestions, as we didn't type anything but just
clicked on a link on their page. And indeed "Try again" sometimes works.
