README

Rev1

  • Tested in Firefox 43. But taken from MXR of Firefox 42 so it should work there as well
  • Per DXR it looks like the path to Loader.jsm changes to resource://devtools/shared/Loader.jsm

Rev2

  • Updated so it shows how to load it lazy, and gives access to the css, js, and html beautifiers

Rev3

  • Updated description
