found a few inconsistencies with the html / js and the moz-central implementation. 1) navigator.mozApps.install(); Expected: Error: install missing required url argument Got: Error: Not enough arguments [mozIDOMApplicationRegistry.install] <-- is this a good enough error message ? 2) navigator.mozApps.install receipts: null in onsuccess: ←- in html / js receipts: [] in onsuccess: ← in moz-central 3) navigator.mozApps.install in onSuccess installTime = undefined in moz-central

Welcome to XPConnect. All of our DOM APIs throw "helpful" error messages like that (try it with, say, window.addEventListener()). Also, I think you mean "onsuccess" and not "onSuccess"?

(Also, moving to Core :: DOM since navigator.mozApps is part of the DOM, not Firefox.)

Don't mean to bikeshed, but the webapps API is hardly about "Device Interfaces"...

David, 1) what philikon said. This kind of error doesn't even reach the API implementation (which is not bad per se). 2) I'm happy to change the behavior on m-c, but is there a spec that defines this behavior? 3) that's a bug. Can you file it on its own?

2)

+ Adding anant to the thread to answer where the spec is defined. + Filing a bug for issue 3. + Updating the test, just wanted to make sure you were aware that the language was different. But I believe it would be good to standardize the text across each platform.

Submitted Bug 763072 to address 2 (specifically that the polyfill/html should copy moz-central). The rest of the bug appears to have been addressed elsewhere.
