I am trying to save a page with Firefox. It's a post on facebook, loaded on its own page. I clicked "view previous comments" so all comments are displayed. I save the page. I then loaded the saved file. "View previous comments" is back, and if I click on it it wants to load the source off of the internet. I tried loading the page again, displaying all the comments again, switching Firefox to offline mode, and saving the page. I got three consecutive "source could not be read" errors. It saved part of it anyway. I loaded the page, and again, "view previous comments" is back. I tried "view page source" from the completely loaded page, and then saved the file from that window, and I get exactly the same results.
Firefox 20.0.1; Windows XP SP3.
