Acrobat/Reader 10: Save button not working for PDFs referenced from long URLs

Acrobat/Reader 10: Save button not working for PDFs referenced from long URLs:
Issue
If you are using Adobe Acrobat/Reader in Firefox/Chrome to view PDF files from long URLs you may notice that  the Save button is not working as expected.  It may be disabled (greyed out), or it may be enabled, but clicking on the button does not bring up the Save dialog to save the PDF to the local file system.
In some organisations the PDF files may be loaded from complex applications which require long URLs to serve parameters with the PDF.  For example:
http://helpx.adobe.com/content/dam/kb/en/837/cpsid_83709/attachments

/Acrobat_Enterprise_Administration.pdf?timestamp=t1115222011102&a=1234567890

&dkmtid=doc&ext=.PDF#FDF=http://server/XML.xfd
The URL above will show the PDF, but the Save button will not work as expected:

Reason
This is an issue with some versions of Adobe Acrobat/Reader 10 in Firefox/Chrome, and will be resolved in a later update for Acrobat/Reader.  The issue occurs when the URL contains more than 259 characters, as Firefox attempts to use this URL as the file-name in the Save dialog.  Such a long URL can exceed a file system limit and therefore the Save dialog does not appear.
Workarounds

• Use shortened URLs to avoid the issue.


• Use Acrobat/Reader in Internet Explorer.


• Use Acrobat/Reader 9 with Firefox/Chrome.

Solution
Ensure you are using the latest available update of Acrobat/Reader 10.  If you require an urgent solution to this issue, then you should contact the support team and request a hotfix for this problem.
