Firefox OS Simulator spontaneously launches


I have Firefox 19 beta running on Windows 7 Professional 64-bit. I had the Firefox OS Simulator installed. I was logged in to the machine with Remote Desktop, but was not actively using it. Instead, I was working in another window in unrelated software.

The OS Simulator appeared to start on its own. I did not click in the Remote Desktop window or use any hot keys to start it. I uninstalled the Add-On immediately. Could there be a security risk?

No, this is a known bug in the simulator, hopefully it should be fixed soon. No security issues.

Tylerdowner, Thank you for taking the time to answer, I appreciate it. Where should I have been looking to find that out on my own, so I wouldn't have to bother you with it? Is there another FAQ base for Firefox OS, or a mailing list?
