I have a (mostly) unmanaged computer stuck someplace not easily reachable that has only one purpose: to display a specific web page on a large screen connected to the said computer's video card. This is achieved by running Firefox on bare X11 in full-screen mode.
Now, the page itself has a script that reloads it every X minutes; however, in case of a network/web server outage, which happen quite frequently and cannot be currently avoided, the browser refreshes the page and gets stuck on the "Address not found" page. As soon as it gets there, there's only one way to get things back: to reload the web page manually.
The question: is it possible to modify Firefox's settings in such a way that it automatically attempts to reload the target page every X minutes while being stuck at the "Address not found" error page? Thank you.
