+++ This bug was initially created as a clone of Bug #914317 +++ This is a regression from https://github.com/mozilla-b2g/gaia/commit/124efab2a7bd71861ad3b00f17eaa884a4300974 In mozbrowser prompt service, it has a title field in the event detail which was never used before. But the patch above accidentally brought this field back. http://mxr.mozilla.org/mozilla-central/source/dom/browser-element/BrowserElementPromptService.jsm#34 http://mxr.mozilla.org/mozilla-central/source/dom/base/nsGlobalWindow.cpp#5446 http://mxr.mozilla.org/mozilla-central/source/dom/base/nsGlobalWindow.cpp#5273 https://mxr.mozilla.org/mozilla-central/source/toolkit/locales/en-US/chrome/global/commonDialogs.properties#20 The actual problem is (1) we don't need this title (2) we don't need b2g gecko to translate the string for us. I wonder there's a way to remove all the translation resource from b2g.
