Package: firefox Version: 84.0-3 On an archlinux system, I noticed the ability to right click the firefox desktop entry, and have both "new window" and "new incognito window." This appears to be achieved in their .desktop file:

The arch solution is nice, as it allows a simple right click action. https://specifications.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html#extra-actions-identifier
