  • You may also miss the “Margins & Header Footer” options used to present in the Page Setup of the old UI.
  • In the release notes, Mozilla states “we’ve improved our print functionality (in Firefox) with a cleaner design and better integration with your computer’s printer settings”

If you want to print something to your printer, you may want to save some ink as well as papers by using the Simplify option offered on Print Preview Page.

Selecting the option removes navigation menus and unnecessary elements such as text or ads on the sidebar.

Note: Reader mode also does this, but it may not be supported on all pages that you want to print.
