Sorry for my poor english
I made an application in FM15 that is used on the Web
The application shows some HTML paginated data and then print with the print command of the browser used.
I have no problem with Safari and Chrome, while Firefox will not let me see the contents of the Web Viewer.
In the web viewer content is so:
"Data: text / html,
Firefox in the web viewer frame does not see me anything
if I open the source of the frame it makes me see the HTML text content but it does not render HTML
