so it must be better right ?

Well that is annoying speaking as someone who's actually used "real" nanoprobes in atomic force microscopy. Why do "marketing" people always nick scientific terms and use them out of context.

He does like his marketing hype and made up techy names, but he has done more to bring security issues to the masses than anyone else, and spinrite has rescued data from a couple of formerly dead hard disks for me, so he has his uses.

shields up is not a comprehensive penetration test - I would take many of its claims with a pinch of salt. ( having personally put machines with remote access trojans through shields up to show how it completly fails to mention them. )

Shields up will test from outside -but leak test http://www.grc.com/lt/leaktest.htm will test from the inside. Most Firewalls are SPI enabled (stateful packet inspection) so will allow in packets from comms originating from that pc, that is why trojans phone home for instructions and the firewall allows the replies, cos the firewalled pc initiated the convo...

For the OP.... There is also a page somewhere on the very useful GRC site that shows what your browser is telling about you .... will edit this soon

Edit ....this page explains why you should possibly worry about a fixed ip and name https://www.grc.com/x/ne.dll?bh0bkyd2 and this will show your browser headers - no MAC addresses. here https://www.grc.com/x/ne.dll?rh1dkyd2 if these links do not work from the front page go to project and shields up.

Has the OP looked at what is in the header of an email ?
