[Bug-gnuzilla] Frustrated with IceCat installation

[hyazinthe]

Hi,

since Firefox 38.0.1 Firefox contains DRM.
That's why I want to change my browser and bumped into IceCat.
IceCat sounds very promising and I'm eager to use it, but
I have installation problems.
I want to verify my IceCat download before installation, but I can't.
I find the necessary .sig file for it, but I can't find the key and the
keyserver ! That's what is frustrating me !

When you download TOR browser, the sig is right below the download
button and the 'what's This' link next to the sig leads to an official site,
naming the key of TOR browser and the keyserver:
https://www.torproject.org/docs/verifying-signatures.html.en

So...
I've found the IceCat file, I've found it's .sig file - 
https://ftp.gnu.org/gnu/gnuzilla/31.6.0/
On what official website do I find the necessary key for verifying the 
signature of this download?
And what keyserver suggests me an official website to use for verifying the 
signature of this download?
