No. The best example of this is mercury which is a lot denser than water. It freezes at a lower temperature than water does.

There are many primary and secondary factors that affect the rate of freezing of liquids of different densities. For example, sample sizes must be the same. The freezing temperatures may differ. Will the cooling temperature be adjusted for different freezing temperatures? Also, the latent heat of fusion (amount of heat that must be removed per gram or pound) may differ. Also, heat transfer from a liquid and then from partially frozen boundaries may differ. Ice is an insulator. The shape of the container may be more important for one liquid than another. How does crystallization progress (if any)? It would require careful experimentation (or tables developed from experimentation) to compare liquids of different densities. Good question.

Water freezes at a nominal temperature.
Liquid nitrogen isn't much different in density,yet it's freezing point is hundreds of degrees lower. There are probably other examples but I have to get outta here.

I believe its more to do with the freezing point of the liquid(s) involved than its densisty. However, the conduction of heat may well be different.
