china has lots of chromium based browsers and they can implement so many enhances and intgegrated things with their system. compared to firefox, newbie has no reason to choose firefox as for china localised firefox. who will use firefox, know what's browser or introduced by others saying that firefox is really pure compared to others. but when the introduced ones to download the browser, they see no diffferent with other skin-changed browsers, it really has no good to firefox. i dont know why you decide it, but in the long run, this way will harm firefox and has no profit for you if you have to locallize, just make the account run in china ,it is ok. i dont know how to orgnize my words, just recommend it for you, firefox. a 13 years firefox user.
