Those words are not used in the menus anymore. Look for 'settings' . If there is a specific option and you cannot find it, share that and we'lll try to provide the explicit menu for you.

David - if I paste a doc/photo that I have received as an email attachment and saved to my computer, when I paste it to another email tbird blocks it. I have gone to settings and then Privacy and Sec and the made sure allow remote content is checked. Still happens. Web search says to check Options or Preferences. What am I missing?
