There are more than one platform that are affected by this, as windows uses it's own hosts file too, so it's not just a libc thing. Every sysadmin and homebrew hacker knows of the hosts file that I'm aware of, regardless of the platform.
FFox has no need to be 'mucking' (which I understand to mean to 'write to') with hosts: it needs to read it and parse it.
Failure to do so will always generate an endless stream of "hosts file isn't being honoured" style bug reports. I think you would agree with me that the FFox maintainers & dev's have got better things to do than to answer WONTFIX on the same fault again and again.
