Created attachment 821670 [details] Screen Shot 2013-10-24 at 9.26.00 PM.png User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_9_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36 Steps to reproduce: 1.) Open Firefox 2.) Open Firefox OS Simulator in the Web Dev selection 3.) Press (Stopped) button to open the Simulator Actual results: I'm getting an error when launching the Firefox OS simulator Expected results: It should display the Firefox OS simulator without any errors occuring.
It seems that this bug only occurs when trying to launch the simulator, i've tried to push an app on an actual device and it worked without any exceptions.
Here is a workaround: if you run Firefox from the DMG file without installing it, you'll be able to run the simulator, and push to a phone without any problem. Even if you already have a installed version on your computer, it will work: it will just use your actual default profile.
The 1.2 simulator seems to launch fine from the App manager in Firefox 26 ( soon to be in Beta ) - is this also an acceptable workaround?
I'm able to run 1.3 simulator via about:app-manager on Fx 26 also.
