WOW Lou, you are even less active than I am ;-) Just read your reply now and saw you on Steemit. I have plans though for building Steemit presence for... so I am back here and not going nowhere now. It will be nice to see you around here too :-)

As to the Firefox and Chrome. We just need to have one or the other open, we do not need to have both.
Some people swear that they mine almost half more on FF than Chrome, but I am not sure. The difference I got was not so significant.
