Download and install the latest portable setup where you want then run waterfox-portable.exe.

If you have already installed Waterfox™ from the original setup, move the following files :

Then run waterfox-portable.exe and remove Waterfox™ from your computer.


For an upgrade, simply download and install the latest portable setup.



Some modifications have been made through policies to ensure portability:

  • Disable updater : Waterfox updates are turned off.
  • Don’t check default browser : Stops Waterfox from checking if it is the default browser at startup.
  • ‘Know your rights’: Don’t show on first run.
  • WhatsNew: Don’t show WhatsNew on first run after every update.
  • Profile: Profile path is overrided to data\profile folder (see below).
  • A shortcut is created at launch to allow native notifications and removed when Waterfox is closed


Waterfox™ portable can be configured through the main YAML configuration file:

  profile: default
  multiple_instances: false
  cleanup: false
  • profile : Name of the profile created in data\profile\<name> (default default)
  • multiple_instances : Allow multiple instances (default false)
  • cleanup : Cleanup leftover folders (default false)


You can use custom policies by creating data/policies.json file like this one:

  "policies": {
    "DisableFirefoxStudies": true,
    "DisableTelemetry": true

DisableAppUpdate and DontCheckDefaultBrowser are forced to true.
