Thankfully, every mainstream browser provides a set of development tools. You may use Firebug in Firefox, IE???s Developer Tools, the webkit inspector or Opera???s Dragonfly. However, you may be unaware that Dragonfly is a beta product. Like many developers, I used it now and again but found few compelling features to drag me away from Firebug. Until today.
May 5, 2011 marks the release of version 1.0 ??? and I???ve been converted! Dragonfly is amazing. You???ll be familiar with most of the features, but Dragonfly offers more tools, feels slicker and looks better than its competitors.
Definitely worth checking out the new Opera development tool.
