In both Chrome and Opera, goto the URL chrome://password-manager/settings. In Chrome, export your passwords to a CSV file. In Opera, import that CSV file.
Maybe you could use a utility to remove the title from all of those problem PDF files (and in new ones of those in the future). I asked ChatGTP and this is what it said.
