Packaging IceCat extensions with Guix

[Marius Bakke]

Hi Guix,

I read somewhere that Debian packages certain Firefox extensions. I
tried doing the same with Guix, but haven't been able to get IceCat to
load extensions from a directory.

The attached (outdated!) patch adds the "uBlock" XPI to
<guix-profile>/lib/icecat/extensions. I've tried symlinking this to
"standard" system folders (from IceCat source code), and disabled
unsigned extensions, but no luck so far. Maybe someone more familiar
with IceCat internals can try it?

I would love to have my favourite extensions managed by Guix!
