Did you even look up your question on a search engine before asking it?

The dedicated Wikipedia page has all the information you are looking for: http://en.wikipedia.org/wiki/Firefox_OS (spoiler: no it is not)

Correction: yes, it is; it uses Android kernels.

I think it has some lower-level Android bits, I don't believe it has Dalvik though...
