> Does Chrome have in-REPL stack traces? An eyedropper tool? Multiple cursor support?
Yes, No, Yes (both get multi-cursor from CodeMirror 4)
> Sure, the cURL copy thing and style support in the console were first implemented in WebKit (not Chrome or Blink)
small correction: that predates Blink[1] so there's wasn't a distinction between WebKit's Web Inspector and Chrome DevTools back then.
Personally my favorite thing unique to Firefox DevTools is their built-in WebGL debugger, which seems to have gotten a lot more attention from them than Chrome's experimental Canvas Inspection which has some similar aspects. Supporting it helps probably .1% of the number of developers needing better CSS tools and whatnot, so I understand the prioritization, but it's still an awesome tool for those of us who do need it.
