We have paste-on-right-click functionality built on top of xtermjs, which works nicely in Chrome and Edge, however I was notified today that it fails in Firefox. I was surprised. According to compatibility table on MDN, readText() should be supported, and moreover, it should be seamless (with no permission prompt) for same origin content.
However when I inspect navigator.clipboard instance on the console, it doesn't contain readText method at all. Any ideas? Is it even possible to programmatically read from the Clipboard in Firefox?
