I did, it does not change what I said. uBO works perfectly fine on Firefox Mobile and doesn't use much battery. People can prefer uBOL, but that doesn't make it important to the ecosystem.
Out of all the criticism Firefox fans make of the mobile version, excess CPU usage and excess RAM usage are at the top of the list. Maybe high-end phones run Firefox decently now, but not everybody has a high-end phone. If uBOL has a place on Firefox, mobile Firefox is where it's best.
