[dragonfly.opera.com...] : "Opera Dragonfly, coming on May 6th". On an Opera staff member's blog it says that "Opera has been lacking real developer tools far too long, so it fantastic that Opera Dragonfly is ready to launch soon. It won't be feature complete by the first alpha, but we are actively working to improve the tools and adding more functionality as time goes on."

Will this be an Opera equivalent to Firefox's wonderful Firebug tool? It is unclear (to me) how Dragonfly relates to the existing developer tools [dev.opera.com].

Well, it is out. It comes with Opera 9.5. Unfortunately, installation seems to have nuked my 9.27 settings (on a Mac). So I haven't tested Dragonfly, too busy trying to recover things.

One weird thing: if you visit the Dragonfly page with Firefox, there is no download button. It does show in Opera and Safari.

"Its not just the DOM you can inspect. Check out what CSS rules apply to which element, and what rules are inherited or set by browser defaults. Overridden rules are highlighted so you can see what styles are or aren't applied. Support for editing CSS rules will be added in an upcoming version."

Wow! That alone makes me want to play with it - downloading right now.

Just don't let setup overwrite your existing 9.2x version (if any)... Install it into a separate directory.

It is an alpha version, with many features yet to be implemented. One example is monitoring HTTP traffic, which can be very useful when debugging Ajax things.

So, is there anything that DragonFly does that Firebug does not ?

Dragonfly does remote debugging of devices and other Opera instances for one. Live update of the DOM is apparently something Firebug doesn't have either (apparently).

I finally got around to playing with dragonfly over the weekend. Pretty cool.

Where are the server http headers displayed?
