Hello, since some browser updates (I think). It is possible to edit text boxes in a PDF file protected by a password against modifications. When saving the PDF file, the name of the author and the date of creation do not change. When you reopen the edited file with Acrobat or other, the file is still password protected. The security of the PDF file is violated. Is this normal?

We don't support restrictions by default, so it looks OK for me.

Hello, this is a recent modification.

I tried with 2 different versions of Firefox. (A PDF file with editing restrictions). - With Firefox Quantum 68.0.2 impossible to modify the protected file. (Security compliance) - With Firefox Browser 84.0.1 modification of the protected file is possible. And we can save the file keeping the original author, the creation date and the password. Security is completely bypassed and hacked.

I opened this file with Google Chrome, Opera, IE, EDGE, Adobe Acrobat, PDF X-Changer... Cannot modify fields in a protected file.

You can file a bug on this page: https://bugzilla.mozilla.org/enter_bug.cgi , devs could reconsider this behaviour.
