The blackbox support seems like a killer feature. No more debugging minified JQuery! I also can't believe that CSS auto-complete wasn't there before.
I've been using Aurora for the last few months and have loved the experience. It's stable and I get to early access to great new tools. I highly recommend it for any developer looking to use the latest and greatest.
Oh man! Blackboxing is definitely a killer feature!
Also been using Aurora for the past few months and I like it a lot. Better then Firebug on most tasks (not all yet) and less resource heavy and less buggy.
CSS auto completion is really good addition.
Next thing to hope for is improved profiling tools. Still the best profiling tools are in IE. Even IE8 is better than Firebug.
As a front end dev the only thing still keeping me with Safari/Chrome is the visual highlighting of paddings and margins when selecting or mousing over things in the Inspector (as opposed to the dotted border Firefox provides).
This is simply invaluable to quickly get to the bottom of layout issues. It's really unfortunate that they haven't built this in yet, Firebug slows down Firefox for me to the point of being unusable (switching tabs takes 5-10 seconds) so I'm stuck having either Safari or Chrome open together with Firefox just for that 1 thing.
The combination of being able to freely modify network requests before resending them and being able to execute javascript exactly where you want it seems perfect for debugging other people's websites with less friction. Or figuring out exploits, depending on your point of view. The former is going to save me a lot of pain - I've been running Aurora for a year or two now and it's been good to me, but I've slacked on following new features.
Gotta say, I'm finally now more comfortable using Firefox's Dev Tools rather than Firebug...mainly because Firebug has become a slow piece of crap and FF's now runs at more or less with the speed of Chrome's tools.
Only a few minutes ago I was wondering why the variable value was undefined when I paused the execution in js. Now I found out why. I am actually surprised it was not there before. There are still 12 weeks for this to become stable. Black box seems really neat too.
Wow, lots of great features. The progress on these tools lately is awesome. One little feature I'd _really_ like to see is F12 as a keyboard shortcut to open the dev tools, I'd like that consistency with Chrome & IE.
At least in Firefox Aurora 25 there's a small search icon to the right in the inspector. But its search functionality seems buggy...
Edit: It only shows searches as a CSS expression, and it doesn't show the results in the DOM view, only by highlighting individual results on the page (like inspecting that element)
