问题 I have downloaded and installed FIrefox OS Simulator for testing and developing. I want to test some functionalities that are allowed only on certified applications, such as SMS and phone calling, as described here. What should I include in my manifest (.webapp file) in order to access this functionality in the simulator?

问题 I have just started doing research, but I assume that other people might have the same question: Is it possible to read data from different sources for a FirefoxOS application, such as reading from RSS feeds from different domains?

问题 For an art project, I'd like to have multiple distributed devices that can output sound. Firefox OS devices seem optimal. They bring the necessary hardware and I know HTML and JS very well. But I also need a control web server. From my understanding, a Firefox OS device can act as an WiFi access point ("Share Internet"). However, it cannot act as a small web server for other devices that join the network – without any internet connection. The APIs for native apps seem just not to be powerful

问题 I'm developing a Pomodoro Timer app for Firefox OS and I'm having a problem with the execution of it: Once the timer is running the execution is suspended every time the phone goes in low power mode (which is quite typical in my scenario, for the timer runs for 25mins) and is resumed only when the screen is turned on again .
