Bug#645017: iceweasel is unbearably slow at navigating to urls.

[join_doe]

Package: iceweasel
Version: 7.0.1
Severity: important

Dear Maintainer,
*** Please consider answering these questions, where appropiate ***

   * What led up to the situation?
        About a couple of weeks ago i updated my system. Cant remember the
exact time og the packages installed.
        At some point after the update I noticed that browsing the web was
extremely slow. At first i thought it was my connection and so started testing
its download speed - I have 20mb connection.
        It turned out thought the download speed was fine.
        What i discovered was that the initial connection to a site was what
took soooo long. Once the page was loaded navigating the site went at normal
speed.
        However as soon at one navigated to another domain then the initial
loading would take for ever.
        Ive tried uninstalling all addons, and running in safe-mode. Ive even
tried chaning the dns server, but neither helped.
        Ive noticed that the same problem occurs i epiphany, so I am presuming
that a common library is the culprit.

        I've since uninstalled iceweasel and epiphany out of frustration, and
Im now using chrome which does not have the proble - pages load within a
second, whereas iceweasel takes about 10 secs or more.

        I hope this helps.
