I am super stoked they now have a Firefox compatible version. The React team have been working very hard and it shows. I've been working with React for about a year now, building an application using React Native and the libraries and tools are absolutely solid, something other libraries and frameworks are definitely missing.
Gotta admit, one of the things the React team is handing better than Angular is UX, usability, and general newbie-adoption. This looks very polished and useful.
This is really nice, and it's great to see a non-Chrome version, too (working great in Firefox so far). Chrome often gets all the love (and is a great choice) for new dev tool extensions, but many of our clients -- for one reason or another -- can't/won't use Google's browser on intranet-based solutions. It's nice to be able to test/debug on more than one browser (Some of us still have to party like it's 1999).
Awesome. Any idea what sort of timeline we're looking at with this? If weeks, I'll wait. If we're thinking months, I'll look at patching that in myself.
If anyone is wondering how to get it working, unpack it into a folder with your favourite unpacking thing, enable developer mode in chrome://extensions, and use Load unpacked extension to install.
Should fix the "not a chrome webstore whatever nonsense" notice you get.
