Does anyone know of a work around to enable clipboard API functionality over a local intranet without a public domain name? * I use a local server application with a http interface on my home Intranet, accessed via FireFox (a web browser). I do not want the program to be accessed from the internet, and don't have and don't think I want a public domain for my local Intranet server. In the past I have been accessing it from Firefox by book marking the IP address and port. * The program has recently changed from using Document.execCommand() method to the modern asynchronous Clipboard API. * The clipboard API in Firefox defaults to requiring the host is accessed via https (appropriate for public facing internet access) or the host server is run on the same machine as the web browser (127.0.0.1 or localhost). * From a security perspective I'm not convinced I need encryption between computer in my home networks (if that traffic is being intercepted to spy on or modify my clipboard, then my private network has already been severely compromised). As a result of the clipboard API conventions, the program's clipboard functionality no longer works for me. I have tried * looking for a Firefox exception settings, to enable clipboard API functionally over http (vs https) for specific local IP, but could not find how to do that in FireFox * I have tried installing [https://github.com/caddyserver/caddy Caddy] but without a domain name I couldn't get it to reverse-proxy to https Am I missing an easy solution or do local servers need public addresses now.
