Nope... Resetting the microphone permissions does nothing... FIRESTORM is not prompting the OS for mic access, it's not a problem inside the MacOS. The workaround only appears to be working for about 25% of users according to Mac users I've spoken with. It doesn't work for me either. Cult Leader re-posting the workaround that doesn't work for 75% of users doesn't help. The answer was to revert back to the prior release of Firestorm.
I've also learned that similar problems are now cropping up on windows machines. Great QA Firestorm....
