Hi Ralph,

thank you for your help though afraid I might not been being clear. Im a developer not a user. I have created an app and launched it on the market place, but when I try and upload an updated version of my app I get the error. Ive searched every where and cant find how to set the version of firefox os apps.

Have you updated your manifest file: https://developer.mozilla.org/en-US/A.../Manifest#version
