Until now, Firefox is available for ARMv7 based devices only. Mozilla’s Brad Lassey explains why they mainly target ARMv7 based devices in his blog post. According to him, the main reason to choose ARMv7 based devices is to take the advantage of the Thumb-2 instruction set of the ARMv7 architecture. Mozilla’s decision to release its browser Firefox for ARMv6 based low-end Android phone is good as they can take the advantage of large availability of these devices, though little late now. Mozilla will send different apk for ARMv6 and ARMv7 devices to Google Play Store. Google play now supports multiple apks. Version 14 (Firefox 14.0.1) is the current version of Firefox for Android. It has several new features and changes, for example, Android’s native support, Flash, SPDY, WebGL and WebAPI. However, it does not support the ARMv6 devices. [Via]
