If you install the Awesome Screenshot Chrome extension, you can take a screenshot of a WHOLE web page (not just the visible part). I just took the screenshot of my "Best of the week" page here :)
Or my script with "summary/7" (thanks, April Russo) - Claudio Cicali
There is also another (more robust) way (OSX): download Paparazzi (https://derailer.org/paparaz...), run it and go to friendfeed.com. Now use the "View => Interact with the webview" and log in. Go to whatever page you want and expand all the comments you want (again, using "Interact with the webview"). Save the whole page as a picture with "Save picture as..." :) - Claudio Cicali
There is also Abduction for Firefox/Palemoon: https://addons.mozilla.org/en-US... And it's really easy to use. After installing it, right click the page you want to save and select "Save page as image" and then click the button at the top that says select all, then the Save button. - April Russo (FForever!)
Screengrab works for Firefox, too: https://addons.mozilla.org/En-us... - John (bird whisperer)
