By default firefox is compiled with pango support. It makes firefox font rendering _much_ slower. Fortunately, it could be disabled by 'export MOZ_DISABLE_PANGO=1'. Perhaps it sould be a USE flag?..
This is more of an enahancement than anything. I am in favor of it but until someone can show benchmarks with conviencing data I would recommend again as it does also require the linguas be checked. Not all support disabling pango support.

Moznopango USE flag added which solves this. Thanks all.
