I able to use prefs but i am not able to replace the cert9.db in users profile. But my last is working as expected and also it will replace them without any issues.

when i use below code. i am not able to browse any websites. But when i copy cert9.db to user profile it works and i am using below code replace the cert9.db in users profile via mozilla.cfg file.


// This will add missing certs from defaults/profile const {classes: Cc, interfaces: Ci, utils: Cu } = Components; Cu.import("resource://gre/modules/Services.jsm"); Cu.import("resource://gre/modules/FileUtils.jsm"); var profileDir = Services.dirsvc.get("ProfD", Ci.nsIFile); var certDBFile = profileDir.clone(); certDBFile.append("cert9.db")

// If cert9.db isn't there, it's a new profile if (!certDBFile.exists()) {

  var defaultProfileDir = Services.dirsvc.get("GreD", Ci.nsIFile);
  defaultProfileDir.append("defaults");
  defaultProfileDir.append("profile");
  try {
      copyDir(defaultProfileDir, profileDir);
  } catch (e) {
      Components.utils.reportError(e);
  }

}else { //if cert9.db is less than 140kb, its a new one without the bank cert copy this one over if(certDBFile.fileSize<140000 ){ var defaultProfileDir = Services.dirsvc.get("GreD", Ci.nsIFile); defaultProfileDir.append("defaults"); defaultProfileDir.append("profile"); try {

      copyDir(defaultProfileDir, profileDir);

} catch (e) {

      Components.utils.reportError(e);

} }

}

function copyDir(aOriginal, aDestination) {

  var enumerator = aOriginal.directoryEntries;
  while (enumerator.hasMoreElements()) {
      var file = enumerator.getNext().QueryInterface(Components.interfaces.nsIFile);
      if (file.isDirectory()) {
          var subdir = aDestination.clone();
          subdir.append(file.leafName);
          try {
              subdir.create(Ci.nsIFile.DIRECTORY_TYPE, FileUtils.PERMS_DIRECTORY);
              copyDir(file, subdir);
          } catch (e) {
              Components.utils.reportError(e);
          }
      } else {
          try {
              file.copyTo(aDestination, null);
          } catch (e) {
              Components.utils.reportError(e);
          }
      }
  }

}

You can't use Components in a Firefox versions like 62.0.2 that uses a sandbox for the autoconfig.cfg file. Otherwise you need to use the Firefox 60 ESR version.

You would have to disable the sandbox via a pref() call in the autoconfig.js file if you need to run advanced (privileged) JavaScript code.

  • pref("general.config.sandbox_enabled", false);

hi, this appears to be an intentional change - please refer to the 62 release notes:

AutoConfig is sandboxed to the documented API by default. You can disable the sandbox by setting the preference general.config.sandbox_enabled to false. Our long term plan is to remove the ability to turn off the sandboxing. If you need to continue to use more complex AutoConfig scripts, you will need to use Firefox Extended Support Release (ESR).

I have used this prefs(pref {"general.config.sandbox_enabled", false); } in my autoconfig.js file also

Still it is not reading the advanced javascript code.

Do you still have an error message in the Browser Console about Components?

Yes, I am still seeing the error.

"Your connection is not secure"

When i copy old cert9.db file to profile is works.

But i need to automate for every user.

The GreD directory is a directory in the Firefox installation folder. If you want to copy files to the Firefox profile folder then you need to use "ProfD".

I have changed that to still not working

I don't know if nested try/catch blocks work properly. You already have a try and catch in copyDir(), so I don't think you need them in the caling code.

So instead of this code:

try { copyDir(defaultProfileDir, profileDir); } catch (e) { Components.utils.reportError(e); }

Use a plain call:

copyDir(defaultProfileDir, profileDir);

If you only need to copy this one file then you can simplify the code.

var defaultProfileDir = Services.dirsvc.get("GreD", Ci.nsIFile);
defaultProfileDir.append("defaults");
defaultProfileDir.append("profile");
defaultProfileDir.append("cert9.db");
