Capture entire web page from popular browsers

In the past it was necessary to use scrolling capture in HyperSnap, or our own Firefox plugin, to capture the entire web page. This is no longer needed, as the browsers have their own capabilities to do this:
 
Firefox: right-click on the page, press "Take screenshot", then press e.g. "Save full page" at top-right. Then you can download the screenshot as PNG file, or copy it and paste anywhere (e.g. into HyperSnap window, email, Word document etc.)
 
Microsoft Edge: right-click on the page, press "Web capture" in the menu, then choose "Capture area" or "Capture full page"
 
Google Chrome browser: go to Chrome Web Store - Extensions (google.com) and type "screen capture" into the search box. Click to download one of the Chrome extensions that offer such capture, e.g. right now the #1 seems to be GoFullPage.
