Firefox has been working hard to expand the number of devices it supports, but has always been "limited" to devices running Android 2.2 or higher, with moderately good specs — an ARMv7 chip or above, to be exact. Today Mozilla is announcing that it is expanding its support down to lower-end devices, ones that are as far down the line as an ARMv6-based 800MHz processor and 512MB of RAM. Mozilla lists a few devices, such as the HTC Status, HTC ChaCha, Samsung Galaxy Ace, Motorola Fire XT and LG Optimus Q, that will benefit from these looser spec restrictions.
As part of its announcement, Mozilla also points out that Firefox is receiving improvements in accessibility features. Firefox now integrates seamlessly with TalkBack and Android's screen reader functionality, making the browser immensely easier to use for those who are visually impaired.
While we like to focus on the latest whiz-bang top of the heap devices, a vast majority of Android devices sold around the world aren't that high-end. And just because someone doesn't have a high-end device doesn't mean they don't deserve to have more choices in browsers. The wide range of prices and specs that Android can offer is a huge selling point for the platform, and we'd like to see it stay that way.
