Starting from Firefox 57, only Webextensions are supported making XulEditor obsolete.
It seems that Mozilla XUL/XPCOM technology base was not the durable choice...
Options that I identify now are:
- port XulEditor on WebExtension: seems not feasible since UX and API are very limited
- re-implement XulEditor on another JS plateform like Electron
- re-implement XulEditor as a Web application
- other ideas?
