Mozilla has taken to Twitter to promote a "BIG" surprise it plans to unveil next week for Android users. It has something to do with Firefox, going by the imagery the company provided with the announcement and the fact it included the words "Firefox" and "Android" in the original tweet. No need for Sherlock-like investigative skills here.
The tweet sadly doesn't reveal much else about what to expect, though here it is in full anyway:
#Firefox for #Android. Something BIG is coming your way next week. http://mzl.la/KqFX3n
