[Mark Panen <mark.panen@gmail.com>]

Hi,

Using Squeeze amd64 6.0.5

Using Icedove 10.0.3

My preferences>Attachments is empty.

Preferences>advanced>Config Editor does not help when I change the 
string to /usr/bin/iceweasel still opens the Icedove e-mail links in Opera.

network.protocol-handler.app.http;/usr/bin/iceweasel

Any help on this one please, i want to open my links in Iceweasel?
