I want to use the firefox browser as part of a display solution in our lobby to show animated information including live contents from our website. For this I need to be able to launch the Firefox browser in full screen mode when automatically starting the display PC up in the morning. How can I launch the Firefox browser in Full Screen mode, as the display needs to starts unattended.

I tried to close the browser when it is in full screen mode and then hoped the browser would relaunch next time in Full Screen mode as suggested in the Mozilla Firefox forum but this seems no longer to be supported by the latest browser.
