I'm looking into this.

I'm guessing no Luck?

It's on my very long list. Still looking.

So to do this, you'll need to use Autoconfig. You can read more about it here:

https://support.mozilla.org/en-US/kb/customizing-firefox-using-autoconfig

Create a file called autoconfig.js and put it in the defaults/pref directory where Firefox is installed.

autoconfig.js pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

Then create a file called firefox.cfg where Firefox is installed.

firefox.cfg // const {classes: Cc, interfaces: Ci, utils: Cu} = Components;

let migratedBookmarks = true;

try {

 migratedBookmarks = getPref("bookmarks.migrated.ie");

 Cu.import("resource:///modules/MigrationUtils.jsm");
 MigrationUtils.getMigrator("ie").then((migrator) => {
   migrator.migrate(Ci.nsIBrowserProfileMigrator.BOOKMARKS, null, null);
 });
 pref("bookmarks.migrated.ie", true);

}

This code will import bookmarks from IE and then set a pref saying they were imported so it only happens once.

Hello Mike,

This worked, thank you. Also thank you for referencing the page with the AutoConfig information as I quite like the idea of being able to Centrally manage the file if needed.

1) Create a file called autoconfig.js The text in the Autoconfig.js file is: pref("general.config.filename", "firefox.cfg"); pref("general.config.obscure_value", 0); pref("general.config.sandbox_enabled", false);

2) Copy the autoconfig.js file to: "\\%pcname%\c$\Program Files\Mozilla Firefox\defaults\pref\autoconfig.js"

3) Create a file called firefox.cfg This is the text in the firefox.cfg file // const {classes: Cc, interfaces: Ci, utils: Cu} = Components; let migratedBookmarks = true; try {

migratedBookmarks = getPref("bookmarks.migrated.ie");

} catch (e) {} if (!migratedBookmarks) {

Cu.import("resource:///modules/MigrationUtils.jsm");
MigrationUtils.getMigrator("ie").then((migrator) => {
  migrator.migrate(Ci.nsIBrowserProfileMigrator.BOOKMARKS, null, null);
});
pref("bookmarks.migrated.ie", true);

}

4) Copy the firefox.cfg file to: "\\%pcname%\c$\Program Files\Mozilla Firefox\firefox.cfg"
