I cannot open the secure PDF in firefox when I use the 'Preview' button from gmail. If I open the same message in the google chrome browser then it works. Am I going mad, or is there something wrong with firefox?
This is due to the Gmail PDF previewer in firefox not supporting The strong encryption used by mkryptor (AES 256). To view the message either:
1. User the google chrome browser to preview the message
2. Choose the ‘Download’ option next to the PDF attachment, rather than ‘View’. You can then open it in your normal PDF viewer (e.g., Adobe Reader)
