User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.9; rv:33.0) Gecko/20100101 Firefox/33.0 (Beta/Release) Build ID: 20140611030204 Steps to reproduce: I wanted to help a partner on finding more details why his app got rejected. To search through the code I want to download the latest package from https://marketplace.firefox.com/reviewers/apps/review/picsart "Install App" button is available and links to a manifest that I look at and get the package URL from. Actual results: The package is not available, showing an Oops page. Expected results: The package should be there or the Install button disabled. Storage is cheap so we should be able to keep some packages that are a few MB each around for some longer time.
