STR: * install app in http://everlong.org/mozilla/selfupdatinghosted/ * check for update from Settings => in "adb logcat | grep Offline" I see this line : E/GeckoConsole( 1252): Offline cache manifest magic incorect, URL=http://everlong.org/mozilla/selfupdatinghosted/manifest.appcache This should happen if the appcache file doesn't start with "CACHE MANIFEST" but this appcache is obviously correct because it installed before... Problem is : this is the same if the appcache manifest changes, either with a webapp manifest change or without it... So we never get the update notification for an hosted+appcache app ! This is quite strange because I think we got them in the past so this may be a regression. I'd like a confirmation about this too so marking qawanted. Blocking on this... This may be related to Bug 823143 or Bug 830661.

Honza - Any ideas?

The app cache magic error is fixed by the patch in bug 829763

Sounds like this is a dupe then, right?
