Mozilla's mobile platform, Firefox OS, is behind Android in just about every way.
The year-old Firefox OS is not even in the same league in market penetration, and is available on just seven smartphones from five carriers and in 15 countries.
But in one important respect, privacy, Firefox OS is trying to move ahead of Google's Android by offering granular application permissions, giving users more control over what data apps can gather from their devices.
According to a blog post from Frederik Braun, a Mozilla security engineer, Firefox OS version 2.1 will give users the ability to revoke permissions on a granular level for any "Privileged" app downloaded from the Firefox Marketplace.
Similar to Apple's iOS, Firefox OS already prompts users for permission to access certain functions, such as geolocation, use of the camera or recording audio.
Permissions are different for every app, and are generated by the app developers in accordance with Mozilla's app manifest.
