Firefox Developer Edition transfer settings and preferences

I just installed Firefox Developer Edition and after I logged in my Firefox account, it automatically synced all my bookmarks and extensions from the standard Firefox browser (which I use). I was wondering if I can also sync all my settings and preferences for the browser as well as the extensions.

  1. In the Menu bar at the top of the screen, click Firefox and select Preferences. Click the menu button. and select Settings.
  2. In the General panel, click on Import Data under the Import browser data section.

Open another file manager to the thumb drive.Enter the profile folder.Mouse click once, then press A to mark everything. Now Copy Everything to the other profile .
