Supported platforms

Linux
macOS
Windows

Installing

Install the Firefox extension and companion bridge application. Downloads can be found on the website or in the GitHub releases section.

macOS/Windows versions have installers, Linux packages can be installed via the command line:

# Debian/Ubuntu
sudo dpkg -i fx_cast_bridge.deb

# Fedora
sudo dnf install fx_cast_bridge-<version>.<arch>.rpm

Package managers

Arch Linux (AUR) - https://aur.archlinux.org/packages/fx_cast/
```
yay -S fx_cast
```

Building

Requirements

NodeJS
dpkg (for building deb packages)
rpm (for building rpm packages)
macOS (for building macOS installer packages)

Installing dependencies

macOS:

brew install dpkg rpm

Debian/Ubuntu:

sudo apt install dpkg rpm

Fedora:

sudo dnf install dpkg rpm-build

Archlinux:

At the moment, pkg has a bug, until fixed nodejs has to be downgraded to 10.12.0:

sudo pacman -S nvm dpkg
yay -S rpm-org
echo 'source /usr/share/nvm/init-nvm.sh' >> ~/.bashrc
nvm install 10.12.0

Instructions

git clone https://github.com/hensm/fx_cast.git
cd fx_cast
npm install
npm run build
npm run install-manifest

This will build the ext and app, outputting to dist/:

dist/app/
... contains the bridge binary and manifest with the path pointing that binary. install-manifest copies this manifest to the proper location (or adds its current location to the registry).
dist/ext/
... contains the unpacked extension.

Watching ext changes:

npm run watch --prefix ./ext

Launch Firefox and auto-reload on rebuild (run in separate terminal):

npm run start --prefix ./ext

Packaging

Packaging currently only possible for macOS/Linux. macOS packages can only be created on macOS, Linux .deb/.rpm packages can be built on any platform with dpkg-deb and rpmbuild binaries.

dist/app/
... contains the installer package: fx_cast_bridge.(pkg|deb|rpm|exe)
dist/ext/
... contains the built extension in the format fx_cast-<version>.zip.

Build and package app and extension for current platform:

npm run package

Build and package app for linux platforms:

npm run package --prefix ./app -- --platform=linux --packageType=deb
npm run package --prefix ./app -- --platform=linux --packageType=rpm

Package script arguments

--platform "win","mac","linux"
Select the platform to build for.
--packageType "deb","rpm"
Select the package type. Defaults to deb. Only relevant when building for Linux.

Testing

Testing requires geckodriver (or chromedriver for Chrome parity testing). See selenium-webdriver installation instructions (ignore npm install).

Test results will be displayed within the opened browser tab.

npm run build --prefix ./app
npm run install-manifest
npm run package --prefix ./ext
npm test
SELENIUM_BROWSER=chrome npm test

Usage

Extension can be loaded from about:debugging as a temporary extension.

Most sites won't load the cast API unless the browser presents itself as Chrome. The extension includes a method of spoofing the user agent string, sites can be whitelisted via the options page. Whitelist entries are specified as match patterns. To whitelist all sites, add <all_urls> to the whitelist, though this could cause breakage on random sites.

HTML5 media elements have a "Cast..." context menu item that triggers a sender application. Only works on remote (non-local) media that isn't DRM-encumbered.

Cast-enabled websites will load the sender API shim and display a cast button as in Chrome, provided there are no bugs/incompatibilities with the shim.
