Is there any way to provide command-line arguments to the version of Firefox being used by FirefoxPWA?

Currently not (without editing the source code and specifying arguments there). However, I could add a way to provide arguments, maybe using some environment variable and/or additional arguments to the site launch command.

You will be able to provide Firefox arguments in 1.0.0 which will be released soon. There will be a few ways to do this:

• To specify arguments when launching a specific PWA from the command line: firefoxpwa site launch ID --normal-arguments -- --firefox-arguments
• To specify arguments when launching a specific PWA from start/app menu shortcut: Edit the shortcut (details depend on your OS) to provide arguments in the same way as above.
• For all PWAs: Edit FirefoxPWA config file (%APPDATA%\FirefoxPWA\config.json (Windows)/$XDG_DATA_HOME/firefoxpwa/config.json (Linux)/$HOME/Library/Application Support/firefoxpwa/config.json(macOS)) and include arguments as JSON list of arguments. For example:

{
  "sites": {...},
  "profiles": {...},
  "arguments": ["--jsconsole", "--allow-downgrade"]
}

Arguments specified when launching from command line will overwrite config arguments.
