open the icedove mail link in iceweasel

[lina <lina.lastname@gmail.com>]

Hi,

I wish to open the link in icedove by iceweasel, now opens by epiphany.

following the http://forum.mepiscommunity.org/viewtopic.php?f=8&t=28635

I did:

To config thunderdird to use firefox for it's links:
In icedove
Edit->Preferences
then go:
Advanced->General

Click on 'Config Editor' and on editor check for a key:
network.protocol-handler.app.http
(you can make it if it doesn't exist) RIghtClick on the Config Editor 
Background and
As with Firefox
1. From the pop-up menu, select "New".
2. From the next pop-up menu, select "String".
3. In the pop-up dialog box "Enter preference name", enter 
"network.protocol-handler.app.http" No Quotes
4. In the pop-up dialog box ?"network.protocol-handler.app.http" enter 
/usr/bin/iceweasel

but why still not work as expected, the same as nothing being done before,

Thanks,
