Question

当我在Firefox 45.0中打开url资源：///defaults/preferences/firefox.js时，会显示许多根据this page应存储在browser / app / profile / firefox.js中的选项

但我在firefox浏览器目录中看到的唯一文件是：

blocklist.xml  
chrome.manifest  
crashreporter-override.ini  
icons    
searchplugins
chrome         
components       
extensions                  
omni.ja

试图在Linux和MacOS上找到它。

那么这些数据来自哪里？

更新：这是firefox（45.0）的最新linux版本的输出

root@ip-172-30-0-227:/tmp/fireomni# unzip -l omni.ja | grep firefox.js
warning [omni.ja]:  11393365 extra bytes at beginning or within zipfile

     7573  2010-01-01 00:00   jsloader/resource/gre/modules/commonjs/sdk/windows/tabs-firefox.js

此处列出的firefox.js文件不是资源中显示的文件：///defaults/preferences/firefox.js

Answer 1

大多数内部javascript和xml都打包在omni.ja中，这只是一个zip存档。

打开资源：///defaults/preferences/firefox.js包含以下这些行：

//@line 1643 "c:\builds\moz2_slave\m-cen-w64-ntly-000000000000000\build\src\browser\app\profile\firefox.js"
pref("dom.ipc.reportProcessHangs", true);

strings browser/omni.ja | grep "//@line 1643"匹配

也

# unzip -l browser/omni.ja | grep firefox.js
warning [browser/omni.ja]:  30524217 extra bytes at beginning or within zipfile
  (attempting to process anyway)
error [browser/omni.ja]:  reported length of central directory is
  -30524217 bytes too long (Atari STZip zipfile?  J.H.Holm ZIPSPLIT 1.1
  zipfile?).  Compensating...
    82905  2010-01-01 00:00   defaults/preferences/firefox.js

所以数据肯定在那里。

firefox存储资源中显示的数据：///defaults/preferences/firefox.js？
