I recently switched back to FF after many years on chrome and find the dev tools to be as good of not better this time around. Curious which tools in particular you find worse? When was the last time you tried?
Partly it's little usability things:
- There was one time when an HTTP request was failing and I couldn't figure out why, and in the Network tab Firefox wouldn't show any information about it, even the request that went out (other than the URL), whereas Chrome not only showed the headers, it surfaced that it was a 404.
- There's no way to view all source files. You have to go to "Style Editor" for stylesheets and "Debugger" for JS files. I'm not sure how to view the other files that were loaded, outside of the Network tab.
- I do enjoy how Chrome's inspector puts the box layout directly above the computed styles, instead of in a separate tab.
Those all feel like nitpicks, though. It could just have more to do with me not being used to it. Maybe I haven't given it enough of a chance and should give it another try.
Lately though I haven't found myself needing to switch over to Chrome for anything devtools related. This new replay feature makes FF even more compelling (once it comes to Linux that is).
So if you haven't used FF for development recently, you should definitely give it a try.
