v2.3.1

Firefox support 🎉

We're supporting firefox with all the features except running from Firefox DevTools panel (which will come as soon as it will be implemented). Minimal required version is Firefox 48, which should be released soon. For now use Firefox Nightly or Developer Edition.

To build the extension run npm i && npm run build:firefox and load the extension's folder ./build/firefox. It will also should be available on AMO soon.
