Just this week I wanted to do a screenshot of an entire website, there wasn't any built-in solution and I didn't wanted to install an extension to the browser to do that (for privacy reasons), and from the FAQ I see that I can opt-out from the telemetry. Time to give it a try.

SingleFile [1] is an open source browser extension that saves the webpage as a single offline HTML page. I personally prefer this to screenshots because you can do things like select text in the saved HTML page. Also if you don't trust the chrome web store or firefox addon repo, you can download the extension directly from Github.
