=== ARMv6 (experimental) ===
<font color=red>'''Sorry, the experimental ARMv6 builds are no longer available.''' They contained bugs that caused them to crash immediately, so they were no longer useful for testing.</font>
While we'd like Firefox to run on as many phones as possible, we are focusing first on devices that can run current versions of Firefox with acceptable performance. As we improve Firefox's speed and memory use, it ''might'' become possible for us to support ARMv6 phones in the future, but we are not actively working on it now.
=== Known Issues ===
These are some of the bugs in the latest nightly builds. We are working on fixing them.
'''Installation and Add-ons:'''
'''Performance and stability:'''
* '''Fennec causes the Motorola Droid to freeze completely''' when loading certain web sites, or at other random times ({{Bug|602252}}).
* '''Fennec causes the Nexus S to freeze completely''' when loading certain web sites or opening many tabs ({{Bug|624652}}, <font color=green>fixed in Android 2.3.3?</font>).
* '''Fennec's JIT compiler is disabled on Samsung Galaxy S phones running Android 2.1''' because of a bug in their 2.1 kernel, making Fennec slower than on other devices. Galaxy S phones already running Android 2.2 "Froyo" are not affected. ({{bug|601222}}, {{bug|603624}}).
* '''Fennec crashes on some old Cyanogenmod 7 nightly builds''' and other modified recent Android systems versions (including Android 2.3 for the Desire HD) due to a bug in the zlib compression library ({{bug|626051}}).
