How trustworthy is javascript's random implementation in various browsers?

Question

Generally you can't rely on pseudo random number generation in javascript to be even remotely cryptographically secure. You might consider implementing your own PNRG using an entropy gathering system, or perhaps using an external source of random numbers such as hotbits.
