That's... a pretty good question, actually. And no one has asked me it before. The easy answer is that you can still fall back on going to the Saved Passwords window (shortcut: Tools > Saved Passwords, or you can use the toolbar button if you add it), clicking "New", and using the "Guess from current page" button in the editor.

If you really want to be able to use the context menu, there are supposed to be solutions for that. There's an add-on called RightToClick, and others might exist; give them a try.
