Hello, I have created and added to a SharePoint 2013 website a PowerPoint 2013 PPTX document containing hyperlinks. When I log in my Sharepoint site and I click on my Powerpoint document , it opens in my Firefox browser with the Microsoft PowerPoint Web App 2013 and the Silverlight module. When I move the mouse over an hyperlink of my powerpoint document , the mouse cursor changes well in hand which means that my hyperlink is detected by firefox but is inactive when I click on it . I realized it was active when I was still click it , I moved the mouse lightly and leave the click ! It's incredible but true. I do not have this problem with IE and Chrome . Hyperlinks are active when I click on it. Note that I used the latest version of Firefox (42) and the latest version of Silverlight 5.1.40728.0

Thank you in advance for your support. Best regards.
