As great as your smartphone hardware may be, it’s the software that can make or break your user experience. If you’re looking for an alternative on your Android phone, Mozilla wants you to try Fennec for Android, which is available for download now.
It should be noted that the current build of Fennec (previously known as Firefox Mobile) is nowhere near what a complete project should look like. It’s not even in beta testing mode. They’re saying that this build is “pre-alpha,” so I wouldn’t have the highest expectations for reliability.
