Displaying PDFs in a browser
Chrome browser users please note that the latest version (from 8) of Chrome has come out with a built-in PDF viewer.
You need to disable it in order to be able to submit your return through eFiling.
To disable it in Chrome: Enter about:plugins in the address bar and click Disable underneath the entry for “Chrome PDF Viewer.”
The Adobe Reader plug-in will automatically be enabled, if you have it installed.
