Reader plugin gone since Safari 12?
Since I upgraded to Safari 12 on mac os, PDFs seem to now always open with preview instead of the Acrobat Reader, i.e. i get only the small button bar shown below instead of the larger one incl. the "print" button to get to Reader´s printing dialog. Instead, I can only open a local copy and then print.

Reader is set as the default application for PDF, and the hints about enabling the plug-in do not apply, since there is no Acrobat Reader plugin shown in Safari anymore (I think it was there, but did not actively enabled or disabled it since it always just worked).
How can I check whether the Acrobat plug-in is installed? Re-installating Reader did not help.
