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:
The URL above will show the PDF, but the Save button will not work as expected:
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.
- Use shortened URLs to avoid the issue.
- Use Acrobat/Reader in Internet Explorer.
- Use Acrobat/Reader 9 with Firefox/Chrome.
This issue does not happen with the latest version of Acrobat/Reader 11, and will be fixed in a future release of Acrobat/Reader 10.
