Chakra implements LCG algorithm for Math.random. Firefox has switched to XorShift128+. Chrome used to implement MWC1616 and they have switched to xorshift128+ as well. This is a request to update Chakra Math.random implementation to use xorshift128+. Xorshift128+ is an improvement over LCG even though it still is not cryptographically secure. The same algorithm across all browsers serves well on interoperability story.
