I don't have a solution, but have seen this problem.

This could happen in Firefox 75 if:

  • you have not yet entered your Master Password in this session
  • you have a login saved for the site where you're viewing the PDF

However, I wasn't able to generate the same problem in a "clean" profile so some other setting (besides having a Master Password) could be coming into play.

This was fast! Sorry, I didn't find the existing question.

Looks like, no solution at this time, untick "Autofill logins and passwords" have no effect.

Does it make a difference if you set this pref to false on the about:config page?

No, didn't help.

According the other topic, Firefox is asking master password if the pdf is under a domain, where you have saved login credentials and you have not yet entered your Master Password in this session. As jscher2000 wrote.
