And Android 4.1 will get what Market penetration? Chrome already doesn't support the vast majority of phones out there, whereas this Firefox release does.
That's interesting. I used the default Android browser for like 2 minutes and I'm glad it will be gone. However, this will probably make it harder for Opera and Mozilla to compete. The next logical step for them would probably be to work with vendors (or at least mobile carriers) to have their browser installed by default. Opera used to do this with older phones, never saw it with Android (that does not mean it doesn't happen though).
