I had a heck of a time installing Firefox 4 on my new Viewsonic gTablet. I couldn’t find the option in Amazon’s otherwise great App Market. The gMarket site (Handango) didn’t work. Going directly to Google’s own Android Market failed repeatedly because this isn’t a phone. Naturally, I tried installing from Firefox. Success came in the form of the ftp link in the last paragraph before – a long link to type onscreen.
After installation, I set-up Sync. Note that you should use a device that has FF 4 installed and synced to complete the setup. Although Sync works fine in 3.x, the Add a Device function did not work for me in 3.x, but did work in 4.
Download Firefox 4
Firefox 4 for Android is now available. This beta is available for ARMv7 only, and requires Android 2.0 or higher. Please check the system requirements below to see if your device is compatible.
If you have a compatible device without Android Market access, you can also download Firefox for Android directly from our FTP server. [http://ftp.mozilla.org/pub/mozilla.org/mobile/releases/4.0/android-r7/multi/] (Note: You will need to keep Firefox up to date yourself if you do not install it through the Market.)
