I you want to print a "selection" use '''{ Ctrl + P }''' to initiate printing rather than using the Print toolbar button. The "selection" gets lost when going thru Print Preview.

You do have to use Ctrl+p, but there definitely are some glitches with this feature. Depending on the layout of the page, Firefox may print the selection off the right side of the page, or after one or more blank pages, or shrink it too much. Over the years, several workarounds have been proposed to make printing a selection work more like IE -- IE simply places the selection in the upper left corner of the printout instead of preserving its position on the page. Here are a couple add-ons that allow you to isolate the text you want to print in a way that works around the problem: (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). Screen shots in this old post: https://support.mozilla.org/questions/923294?page=2#answer-328405 To view the whole page again, you might be able to right-click Undo remove, or you need to reload the page. (3) Other... I haven't searched for new solutions in the past year, so there may well be some new ideas out there.
