Why pdf files do not print in Adobe, but only in Firefox browser

Before the last update the setting for use Adobe Acrobat instead of the Firefox browser printing worked properly. That is a feature badly needed to make possible fine print settings, which are not available in the browser print function. Before, whenever I created a web based print output it automatically opened in Adobe Acrobat and could print from there easily. Now, since the last update, in order to achieve the same print result first I have to print into pdf, download onto my computer as pdf, and then open the pdf automatically in Adobe and make the print. Afterwork is to delete the downloaded, printed file. Can you please let me know how to change settings so to to get back the automatic printing from Adobe Acrobat instead of browser? In settings the default for PDF files is set to Adobe Acrobat, but that does not seem to matter.
