It probably has to do with your OS rather than your browser, since emoji are part of unicode, and presumably in order to use later versions of unicode, your OS has to be updated.
You can check what version of unicode your device supports:
http://emojipedia.org/unicode-6.0/The crab is unicode 9, and the fist is unicode 6 so at least the fist should theoretically display fine on both my device and your device.
