How do I solve this problem:Photo's no longer displayed (Adobe Flash player 13,0,0,214) in online photo album maker (Webprint.nl) after update to Firefox 29.0.1

Question

After I (automatically) updated to Mozilla Firefox version 29.0.1, the online photo album crreator of Webprint.nl no longer displayes the photo's that I uploaded.
The photo's are displayed again when I use an older Firefox browser (version 28.*) from an another computer. This is my old (WIndows Vista) computer that I use when my new Windows 7 computer has problems.
It looks like the new Firefox has a problem with Adobe Flash player 13,0,0,214; which is the newest version according to Adobe.
Please help!
