Why can't I Share websites with friends any more. That option is gone!

[domcomm]

I recently upgraded from Sierra to High Sierra, and Firefox upgraded to a newer version. Now if I want to share a website with a friend, I can't, because that option is no longer there. I go to File, Share, but all that is there is Messages and More… Is there a way to get it back?

I run Windows, so I don't know: does Firefox on Mac have File > Email Link... ?
