Console Guide

The project provides a firefoxpwa console program that can be used to install, launch and manage web apps instead of the extension.

The executable should be automatically added to PATH on installation. To display the built-in help, run firefoxpwa --help or firefoxpwa <command> --help.

The project also provides shell completion files for Bash, Elvish, Fish, PowerShell, and Zsh.


On Windows, all completions are installed into the completions directory in your chosen installation directory, but you need to manually load them into your shell. When using DEB or RPM packages or installing the package from Homebrew or AUR, completions for Bash, Fish, and Zsh are automatically installed into required directories and loaded by shells.

For other operating systems or shells, you can find the pre-built completions in build artifacts and release attachments, or build them along with the project (they will be in target/{PROFILE}/completions).

Runtime Management

To be able to launch web apps, you need to download and install the Firefox runtime:

firefoxpwa runtime install

The runtime is completely separated from your main Firefox installation and does not interfere with it or other Firefox installations.


To install runtime on Windows, you need to have 7-Zip installed. Installing the runtime will automatically trigger the 7-Zip installer if needed, which may require accepting User Account Control prompt. You can also manually install 7-Zip or use your existing 7-zip installation. After the runtime is installed, you can delete 7-Zip manually.


Instead of using the default runtime (normal Firefox), you can manually download an alternative Firefox version or Firefox fork (LibreWolf, IceCat, Waterfox, etc.). However, please keep in mind that compatibility with other or unofficial runtimes not guaranteed.

You can check FAQ for instructions.

You can uninstall the runtime, but you won't be able to launch web apps until you install it back:

firefoxpwa runtime uninstall

You can also patch the runtime with the current globally installed version of patches.

firefoxpwa runtime patch

This is useful after (re)installing a custom runtime, or if you are experiencing problems with web app launching. You might also need to patch profiles, which you can do from the extension.

Profile Management

Web apps use a separate profile system from the normal Firefox, so data such as installed extensions, passwords, logins, etc. are not shared with your normal browser profile. This is used to make web apps more reliable and allow additional customization. If you want to sync data between your main and web app profile, it is recommended to use Firefox Account or a third-party sync solution.

By default, web apps are installed to a common profile with ID 00000000000000000000000000.

You can also create separate isolated profiles and install web apps there, which allows you to install multiple instances of the same web app with different accounts.

Creating a Profile

firefoxpwa profile create --name PROFILE-NAME --description PROFILE-DESCRIPTION --template PROFILE-TEMPLATE

This will create a new profile directory and return its ID. You will need that ID later to install the web apps into the profile or remove it.

The name and description arguments are optional. If omitted, they are set to empty values.

The template argument is also optional. If specified, all contents of the provided template directory will be copied to a newly-created profile. This is useful if you want to create a new profile with the same extensions, settings, etc. as an existing one.


If you want to use an existing profile as a template, make sure it is not running before copying as a template. Otherwise, it will contain lock files that can cause errors when creating or running a profile from template. You can check FAQ for more details.

You can check a list of most available profile properties and settings.

Removing a Profile

firefoxpwa profile remove ID

This will completely remove the profile and all web apps installed in it, including all user data. You might not be able to fully recover this action.

The default profile cannot be completely removed. Trying to remove it will just clear all web apps and user data, but keep a profile ID in the profile list.

Editing a Profile

firefoxpwa profile update ID --name NEW-PROFILE-NAME --description NEW-PROFILE-DESCRIPTION

This will change profile's name and description, while keeping installed web apps intact.

Both arguments are optional. Omitted arguments will not change profile's properties. Setting arguments to an empty value will clear their properties.

It is also possible to apply the profile template to an existing profile, with similar behavior as when creating a profile.

Listing Profiles

firefoxpwa profile list

This will print all your profiles and web apps installed in them, including their IDs. You will need profile IDs to install a new web app into a separate profile or remove a profile, and web app IDs to launch or remove them.

Web App Management

Installing a Web App

firefoxpwa site install MANIFEST-URL --profile PROFILE-ID [...]

This will download the web app manifest, parse it and register the web app to the OS. It will also return the web app ID that you will need to launch it.

The profile is optional and will default to the shared profile. Other arguments are available; you can check them in the program help. You can also check a list of most available web app properties and settings.


You cannot re-use the same name for multiple web apps, because newer ones can overwrite menu entries for existing web apps. You should also be careful not to re-use the name of an existing native app, because it can also overwrite its menu entry.

You cannot install multiple instances of the same web app in the same profile, because they would actually be the same instance. Instead, install each instance into a separate profile.

Uninstalling a Web App

firefoxpwa site uninstall ID

This will uninstall the web app and remove it from the list. However, web app data will stay and will be reused if you later install it again in the same profile. To clear the data, do that through the app browser, or also remove a profile.

Updating a Web App

firefoxpwa site update ID --name SITE-NAME --description SITE-DESCRIPTION [...]

This will change web app's information, such as name, description, icon, etc. It will also (unless disabled) update the web app manifest and icons, and re-apply the system integration.

You can check all available arguments in the program help. Omitted arguments will not change web app's properties. Setting arguments to an empty value will clear their properties.

Launching a Web App

firefoxpwa site launch ID

This will launch the Firefox browser runtime and open the web app.

To launch a web app with a custom start URL, use the --url argument. When the tabs mode is enabled, you may specify this argument multiple times to launch URLs as multiple tabs. To launch a web app with a protocol handler (on supported web apps), use the --protocol argument.
