For those of you who are interested in learning code - this new feature of Firefox is AWESOME! I think it will be a HUGE asset to most NC's, because you can play with the CSS of your network without having to worry about messing anything up. It's already active on my Firefox too:)
You can find a bit more info about these features here: http://www.mozilla.org/en-US/firefox/features/#cuttingedge
Dear Janette - great tools! Thanks for the heads up. In IE Explorer 9 you can view developer tools pressing F12. More information here: http://msdn.microsoft.com/en-us/library/ie/gg589512(v=vs.85).aspx
You're welcome:) And thank you for sharing your info too!
