When installing an app via the local app page to a device that forbids certified apps, we get an alert dialog with just "[object Object]".

Reproduced this issue on Nightly from 2013-09-18 with 1.2 Simulator by using a packaged app (email-drawery): an alert with "[object Object]" is displayed when I hit the DEBUG button. 

On Firefox 26 beta 6 (Build ID: 20131118212339), latest Nightly (Build ID: 20131121030201) and Aurora (Build ID: 20131121004004) on Windows 7 64bit, Mac OS X 10.9 and Ubuntu 12.04 32bit, I get an alert dialog with “installationFailed: Installing certified apps is not allowed” (screenshot: Is this the intended message? And is there any need to verify with a device, not only with the Simulator?

The original report is about having a cryptic error message ([Object object] ...) instead of a human comprehensible one (certified apps is not allowed).
So what you describe here sounds good.
Then, there is this behavior difference between 1.2 and 1.3 with certified apps, I think that is due to bug 927108. Its patch has landed on 30th whereas the simulator xpi for 1.2 is based on gecko of the 28th. (you can see gecko/gaia build date in about:addons. The simulator addon version ends up with a date.

I'll spawn new builds of 1.2 and 1.3 addon right now!

With the 1.2 (build date: 20131125) and 1.3 (build date: 20131126) Simulator on Firefox 26 beta 8 (Build ID: 20131125215016) with a packaged app I get no alert, but in the Console I see the warning: “The Web Console logging API (console.log,, console.warn, console.error) has been disabled by a script on this page.”
With a device, the above warning is not initially displayed. Although, after I close and reopen the Console it's shown everytime.

Is this expected?

I think that because bug 915881 landed before this one and allowed installing certified apps.
So with devices/simulator including bug 915881, the app will install and you will be able to debug them.
But without this changeset and with this patch, you should get a meaningfull message telling you that installation failed.

With Fx 27 beta 5 (20140109165205) we have the same behavior as for Fx 26 beta 8 described in Comment 8.

The <<'certified' apps are not fully supported on the App manager.>> message is displayed and the certified apps can be updated/debugged without any alerts.

Marking as verified (per Comment 8 and 9).

Alexandre please change the status flags if there is something I misunderstood. Thank you!
