"Take a Screenshot" has been moved out of the page actions container on the location bar and has become a standalone toolbar button. You can drag this Screenshot button in customize mode from the Customize palette to the toolbar or to the overflow area. You can also use the "Ctrl+Shift+S" keyboard shortcut (Windows/Linux) and Right-click on an empty part of the page and select Take Screenshot. *https://support.mozilla.org/en-US/kb/take-screenshots-firefox *https://support.mozilla.org/en-US/kb/customize-firefox-controls-buttons-and-toolbars Also make sure that Screenshots isn't disabled.
