Hi there, You're currently posting in the English forum and we can't guarantee that a community member who speaks your language will be able to assisst you here. However, I looked up with a translation tool and it looks like your having issue with Chinese translation. According to this [https://connect.mozilla.org/t5/ideas/support-chinese-translations/idc-p/91607/highlight/true#M48693 Mozilla Connect page], CJK languages including Simplified Chinese are not ready for Firefox for Android. The current workaround it to use Beta/Nightly version in the meantime. The good news is, it's highly possible that we'll finally release CJK languages on the upcoming version 141, which is scheduled to go out on July 22. So please keep an eye out for upcoming release!
