Currently USE="-mozbranding" uses that ugly globe icon familiar from Ubuntu. I'd recommend shipping IceWeasel (GNU version of Firefox) when that flag is used, or at least using the IceWeasel icon (as seen on the Wikipedia link) with "Bon Echo".
IceWeasel =! Firefox, so really I don't see why we should ship it under the same name or use its logo.
Not enabling branding doesn't mean we ship iceweasel instead. Using the iceweasel name or logo would just lead to confusion in my opinion, so I'm closing this bug as wontfix.
