It really is nice that we are being flattered so much and told how much we're loved from the bottom Mozilla's heart...

But I can't really see what is so great about this new tool. It looks like everything that is already available. It may have been updated so that it is on par with Google's dev tools but was a publicity stunt really needed in order to do this?

If you want to download the new edition you can get it straight from the Mozilla website. Download it and give it a try. It does seem to be well developed for mobile emulators.
