Fedora 34 allows to install Firefox without this library however if you run Firefox this could be seen in console:
[GFX1-]: glxtest: libpci missing
pciutils-libs provides the necessary library.
libpci is provided by pciutils-libs which is required by Firefox 89.0.
also rpm -q --requires firefox
gives me pciutils-libs
so it should be already there.
