Since XULRunner had been discontinued for over a year?

What will happen if there is a serious bug/security flaw ? I guess there is no way to port komdo to now popular shells like Electron or CEF , since this is so much deepened on XUL and XPCOM.

Evolus Pencil : tho , rewritten from scratch with latest tech and Electron. It is doing awesome,

XULRunner itself is essentially just a bootstrapper for the Mozilla framework. Any bugs and security flaws will likely primarily be in Mozilla. If there are significant bugs in XULRunner then we are capable of resolving those internally.
