Firefox for Android

Firefox for Android is part of the Fennec project to bring the Firefox web browser to mobile devices. For more information about Fennec, see the Firefox Mobile web site.

• Latest Version: Beta 2
• Optimized for: Nexus One, other phones with ~1 GHz ARMv7 CPU and 800x480 display
• System Requirements: Android 2.0 or higher, OpenGL ES2.0, 256 MB RAM, 40 MB phone storage available

Status

Firefox for Android is in very early development. Stay tuned and follow us on Twitter and Facebook to hear about new releases and other announcements. Or read our developer blogs to follow our progress.

We have not yet set a date for the first release of Firefox for Android, but we are tentatively planning for a release in early 2011. See Mobile/Planning/2.0 for more information.

Download Beta

Firefox 4 beta for Android is now available.

1. Check the system requirements below. This beta is available for ARMv7 only, and requires Android 2.0 or higher.
2. If you installed unofficial or nightly Fennec builds, you will need to uninstall Fennec before installing the Firefox beta. This will erase your profile.
3. Point your phone's web browser to firefox.com/m

Download Nightly Builds

If you want to develop, test, or preview the next release of Fennec, you can download a nightly build:

1. If you have already installed a version of Fennec that is not a nightly build, you will need to uninstall it first. This will remove your profile and settings.
2. Download the nightly build directly onto your Android device by scanning the barcode below, or by entering the URL in the Android browser.
3. Open the fennec.apk file when it finishes downloading.

You can also try out Fennec on other platforms, including on your Mac, Windows, or Linux PC.

ARMv7

For Android devices with ARMv7 (Cortex, Snapdragon, Hummingbird) processors, like the Nexus One, Droid X, Incredible, Desire, EVO 4G, or Samsung Galaxy S. (See below for a longer list of phones.)

ARMv6 (experimental)

For devices with ARMv6 processors, like the HTC Hero, Legend, Droid Eris, Wildfire, or Samsung Moment. (See below for a longer list of phones.)

New: ARMv6 builds are broken for the last few weeks on some or all devices. See this bug for details and please comment there if you can provide more information.

Note: The ARMv6 build is new and not widely tested. Many older Android phones do not have enough RAM or storage to run current Fennec builds. Fennec's visual design is not yet optimized for lower-resolution displays (bug 590817).

Known Issues

These are some of the bugs in the latest nightly builds. We are working on fixing them.

Installation and Add-ons:

• New: Fennec nightly builds require Firefox Sync 1.6 beta or a nightly build of desktop Firefox ("Minefield").
• Adobe Flash and other plugins are not supported yet.
• Firefox cannot be installed on AT&T phones, because AT&T disables installation of non-Market apps. A future version of Firefox will be available for these phones through the Android market. Developers can install Firefox using the "adb" command from the Android SDK.

Performance and stability:

• The Fennec interface is less responsive when first syncing with a large Firefox profile (bug 606062).
• Fennec crashes at startup on the Acer Liquid and Liquid A1. (bug 606194). Note: Fennec works fine on the Acer Liquid E.
• Fennec causes the Motorola Droid to freeze completely when loading certain web sites, or at other random times (bug 602252).
• 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).

User Interface:

• Text does not wrap to fit the screen after zooming in, as it does in the Android browser (bug 578179). Easy Reading is an experimental add-on to implement this feature: http://bit.ly/easy-reading
• Copy and Paste do not yet work for text or form fields in web pages (bug 611741).
• Fonts in some languages (including Persian, Arabic, and Gujarati) do not work in Fennec for Android (bug 609649).

Keyboard:

• Fixed in nightly builds: You must hold down the Shift/Alt/Fn key while typing numbers/symbols/capitals on a hardware keyboard (bug 599811).

System Requirements

Fennec requires Android 2.0 or later. Installation requires about 17 MB internal or SD card storage.
