Improved stability with CyanogenMod 10 (Firefox for Android)
It may be unusual for a developer to spend time improving the performance of their app when it’s used on a third-party OS that is maintained by volunteers and not officially supported by mobile device makers. But that’s what Mozilla did with Firefox for Android. They improved the browser’s stability running specifically on CyanogenMod 10. This unofficial, aftermarket Android OS is built on the official open-sourced release of Android 4.1, codenamed Jelly Bean.
