Display PDF in new TAB

Hi @anon29869905 thanks for the reply,

I totally agrree with you in this case because the security is always important.
Maybe you know a browseraddon as workaround ?

Or some hints in form of documentation for coding custom modules and install via the system → packages → installbutton as mention in this post ?

Because this is really a big deal for us and costs so mutch time in our workflow bacause we need to handle with a lot, really a lot of PDF files.
