Up to v8 of Acrobat Full Product (not Reader) I could set a web address into the preferences in the markup section, then if I opened a PDF file from that same web address via a browser then Acrobat would enable the annotation toolbar. From Acrobat v9 the preference settings 'appear' to have been changed so that this is not possible.
Can anyone tell me how to enable this capability under Acrobat v9?
