"Bookmark this page" option in Bookmark drop downs is replaced by "edit this bookmark" option - so can't add a bookmark.
As in question i.e: "Bookmark this page" option in Bookmark drop downs is replaced by "edit this bookmark" option - so can't add a bookmark now. Recent problem - no problems last week. A recent Firefox update perhaps?

If you see "Edit This Bookmark", then you've already bookmarked that page.
If you want to be able to create duplicate bookmarks, install the following add-on.
You can also open the bookmarks sidebar via the "View Bookmarks Sidebar" button in the "Show your bookmarks" button next to the star and drag the tab or "Site Identity Button" (globe/padlock) to a bookmarks folder in the sidebar.
- You can toggle the Bookmarks sidebar off/on via "View > Sidebar > Bookmarks" or "Ctrl+B" (Command+B on Mac)
