Links are messed up (author, series)

Author pages: Links popup opens okay. Can add links. Edit pencil has gone away.
Series: Links popup opens okay. Can add link info, but Save button does nothing.

Running latest Firefox (80.0.1/64-bit) under Windows 10 Home (up to date).

Series: Save button indeed saves a link, but it doesn't seem to do anything. Must close the popup to find out that link got added.

Author pages: Edit pencils are also missing under Opera (latest version: 70.0.3728.178).
