Bug#745813: iceweasel: strange web connection problem

[xavier grave]

Package: iceweasel
Version: 24.4.0esr-1
Severity: important

Dear Maintainer,

On my kFreeBSD/Debian system I encounter the following 
connection/display problems :

  * launching iceweasel on the command line without any url
    - I can't get a byte from the web
      even from the Iceweasel Start Page search engine
    - addons system display the "What are Add-ons?" message
      where it complains about no connection :
        "When you're connected to the internet,"...
    - about:config won't display in any tab
  * launching iceweasel on the command line with an url
    - I get the url web page
      I can navigate in the displayed page, even middle button click is 
operational
    - I get the about:config page if specified on the command line

I can reproduce the addons behaviour with icedove.

Thanks in advance, xavier grave
