Following a trademark violation report (#4) from Mozilla, Thunderbird portable has been named Stormhen portable on Portapps. Nothing changes except its name.


Some modifications have been made through distribution preferences to ensure portability:

  • Multilingual : All languages are included in app/langs and can be enabled in config file (see below).
  • Disable updater : Thunderbird updates are turned off.
  • Don’t check default mail client : Stops Thunderbird from checking if it is the default mail client at startup.
  • Profile: Profile path is overrided to data\profile folder.
  • Disable WinSearch integration: Don’t use Windows Search to search for emails.
  • Add-ons: Disable compatibility checking.
  • ‘Know your rights’: Don’t show on first run.
  • WhatsNew: Don’t show WhatsNew on first run after every update.
  • Crash reporter: Disabled.
  • Calendar: Official multilingual Calendar extension used to handle locales switching.
  • GnuPG Agent: Automatically set GnuPG Agent path to be ready to use with Enigmail extension (see below).


Stormhen portable can be configured through the main YAML configuration file :

  cleanup: true
  multiple_instances: false
  disable_telemetry: false
  gnupg_agent_path: ""
  locale: en-US
  • cleanup : Cleanup leftover folders (default false)
  • multiple_instances : Allow multiple instances (default false).
  • disable_telemetry : If enabled, telemetry is not uploaded (default false).
  • gnupg_agent_path : Path to GnuPG agent gpg.exe. If empty, Portapps will search in PATH or will use the embedded version.
  • locale : Locale located in app\langs can be used to change UI language without .xpi extension (default en-US).
