Improve Chinese translate.

I want to give you some suggestions about Chinese translate.
For example, all the dates such as Jan 1 should be “1月1日” in Chinese, not "1月1", and M Tu W Th F such like these should be translated to “星期一”(M), "星期二"(Tu),"星期三"(W),"星期四"(Th),"星期五"(F),"星期六"(Sa),and "星期天"(Su) but not “一 二 三 四 五”, Firefox and Thunderbird shouldn't be translated
