Wouldn’t right click>save web page as accomplish the same thong?
If you save in Archive.is, it saves it online and also shows if the media outlet changed it. That came in handy when Trump claimed he was wiretapped and Obama denied it. We were able to pull it up via a NYT front page story that they later edited to try and hid, thanks to archive.is.
It also saved the complete webpage, not just the HTML. And if offers the option of a screenprint as well, which you can download.
