Hello, I am wondering how to deal with this error (manifest_url_error). I have a mac and also am running firefox os simulator 1. I cannot download this specific app (Zirma) from the marketplace, although I get the error on lots of other ones. Thanks much for any help! See screenshot. Thanks!! Jon

Hi Jon,

I was able to install and run Zirma on both my Flame device, running v2.1, and on WebIDE's simulator, running v2.0 and v2.2.

Please be sure to try the latest version of the simulator:

• https://developer.mozilla.org/en-US/d.../Firefox_OS_Simulator

Additionally, please keep in mind that the simulator is only a run-time environment. There are some features or applications that may not run as expected in the Simulator.

Thanks for the reply. I have downloaded the simulator, (2.0) and its in my add ons, but how do I run it?

Hi Jon Gregory,

Go into Tools > Web Developer > WebIDE and then select the "runtime environment" to download or run a specific version of Firefox OS simulator.

I hope this helps. Please let us know if you have any other questions about your Firefox OS device.

Thanks,

- Ralph
