Mozilla to Announce ‘Something BIG’ for Firefox on Android

According to the Twitter teasing Mozilla is preparing a big Firefox update for Android. The picture shows what it is going to look like.
It is a bit difficult to imagine what that “BIG” will be, but if taking into account not so many Firefox goodies the browser has seen on Android, it is safe to assume announcement is in this ballpark.

The Google I/O conference will take place on June 27; who knows may be Mozilla will make its announcement during the event.
But if Google thinks of announcing Google Chrome Browser as the default from Jelly Bean 4.1 onward, this may be bit awkward.
It is only left to wait….
