I have a website with a manifest that validates (http://manifest-validator.com/), and files are clearly downloaded since the "progress" event is fired for each file - but, window.applicationCache.status is always 0 (which mean the website does not have a cache manifest). This is in Firefox 11.
This is at first load. When i refresh the page after the manifest is donwloaded, the applicationcache status if first checking, and the idle - which is correct.
Any ideas?
