In what browser is Flash still required? I've been doing:

    to_clipboard = (text) ->
        textarea = document.getElementById "copy-workaround"
        textarea.value = text
        textarea.select()
        document.execCommand "copy", false, null

In chrome for years.

That code doesn't work (at least in ordinary page scripts), as far as I can tell.

You're entirely right, after looking into it a bit, it seems it's blocked now in everything but content pages (which is where I use it)
