Even when you get the printout, the results are sometime surprising because Firefox may preserve parts of the page layout and position the selected content too far to the right or not on the first page. If you have that problem, you may need to use a workaround. Here are a couple add-ons that allow you to isolate the text you want to print in a way that usually works around most selection printing problems: (1) Print Edit - https://addons.mozilla.org/firefox/addon/print-edit/ With this extension, you call up Print Preview and then make your selection there before printing. (2) Nuke Anything enhanced - https://addons.mozilla.org/firefox/addon/nuke-anything-enhanced/ With this extension, you select in the page normally, right-click, and choose Remove Everything Else. Then you can print normally (i.e., don't choose Selection in the Print dialog).
