There should be no need to install anything as root,
unless you make a habit of logging in as the root user
and work from there (not recommended).

(Except the guix daemon itself maybe? But that's "sudo guix pull"
I think, not "sudo guix install guix". I'm on Guix System
myself.)

Which icon are you looking at? The icon in a desktop menu?
The ‘cat around a globe’ image you'd see on ‘new tab’ windows
above the search bar? The same image, but downscaled, before
‘New Tab’ in the tab bar?

I can use IceCat just fine from the terminal (Guix System),
more details are needed, ‘I can't run it’ is rather vague.
Is there any log output, does IceCat start but crash soon,
maybe ‘bash: icecat: command not found’, ...?
