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: 4.0 beta 5
• Optimized for: Nexus One, other phones with ARMv7 CPU and 512 MB RAM
• System Requirements: See the list of supported devices below.

Status

Firefox for Android is in 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 Firefox 4 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 Firefox 4 beta 2 or earlier, please uninstall Firefox before installing the latest version. This will erase your profile. (This is because of a one-time change; future updates will not require you to uninstall and reinstall Firefox.)
3. Point your phone's web browser to firefox.com/m

If you have trouble installing Firefox from the Android Market link on that page, see this support article for help.

Download Fennec Nightly Builds

If you want to develop, test, or preview the next release of Firefox, you can download a nightly build. Nightly builds are named "Fennec." You can install the Fennec nightly build alongside the official Firefox beta or stable release.

1. Download the nightly build directly onto your Android device by scanning the barcode below, or by entering the URL in the Android browser.
2. 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, Tegra) 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.)

Note: The ARMv6 build not supported, and is known to crash frequently. It might fail to run at all. Many older Android phones do not have enough RAM or storage to run current Fennec builds.

Known Issues

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

Installation and Add-ons:

• Adobe Flash and other plugins are not supported yet (bug 630007).
• Starting the app for the first time takes a while while it installs some files and sets up a profile. Later startup times are much faster.

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).
• 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 Cyanogenmod 7 nightly builds and other modified Android systems due to a bug in the zlib compression library (bug 626051).

User Interface:

• Letters sometimes appear in the wrong order when typed on a hardware keyboard (bug 634555).
• Copy and Paste do not yet work for text in web pages (bug 611741).
