I have a computer running Windows Vista setup as a kiosk. It runs Firefox and RKiosk addon and in it, there's splash page made of html with a bunch of images acting as links leading to pages with contents (PDFs, videos and images). When a user browses and leaves the kiosk at any content page, upon idling for a period, a Javascript function detects inactivity and redirects it to the splash page.
Now what I am encountering is, there's a screensaver, upon wake up, would make Firefox to display a blank page. Firefox by which should be on splash page displaying an html page with a bunch of images. The weird thing is Firefox doesn't crash but remains blank. My observation is that this screensaver is the crux of the problem. Before anyone suggests me to turn off the screensaver, I can't, it's a requirement and let's leave it at that.
So I have been experimenting with a lot of settings and even done some optimization to Firefox (putting a higher cache value, etc etc) to no result, so here's a few questions which I hope the collective minds here would answer:
Has anyone been in similar situation before and came up with a fix?
Can we make Firefox to restart periodically upon inactivy (no mouse keyboard event detected for a number of minutes?) or upon screensaver activation? Or any program that could schedule restart upon crash or inactivity?
I am looking for general ideas what might actually caused this as I am open to theories that my observation could be wrong.
