I tried to verify the bug 54998, but I could not because it seems that selectLocale() can not work on nightly build. When I select View->Languages and Web Contents -> English(US), on 0.8.1: --> set new lang, langcode=en-US-- But on nightly: --> strres.js: selectLocale() failed! Any changes to break setLocale() after 0.8.1???
