I just bought the adobe acrabat DC pro, after installed, it can be seen in the chrome and IE extends, but it cannot be seen in the firefox 46, OS is windows10, would someone can tell me why? thanks.

Actually I'd like to use the adobe acrobat to view it, not only view it, but also need this to create the PDF file from the HTML pages.

Now the acrobat DC pro works fine with IE, but cannot work with firfox, even cannot see the "create PDF file" button in Firefox.

OK, finnaly it is a small issue, I can make it from IE.

thanks.
