How do I get the "Install Missing Plugin" yellow bar to appear in firefox when flash is not installe
- by Janak
My rails website uses the open_flash_graph plugin to generate flash graphs for my clients. If a customer doesn't have flash installed, it doesn't display any messages, it simply doesn't show any graphs.
I've noticed that if I go to other websites that need flash, I get a yellow bar at the top of my firefox window that offers to "Install Missing Plugin".
I assume something in the HTML lets firefox know that this webpage needs flash. What code do I need to add to my website to make this work?
