I have been able to open files on this family history research site in the past with Java but all of a sudden nothing will open. Previously: I would click on one of the links, and it would just open. Now: a grey box pops up asking what I want Firefox to do with this file. When I select "open with Java web start Launcher" it says "Application not found."

Unfortunately, I can't post the actual links, but if you select any options from the drop-down boxes on this site, some links in red will appear at the bottom of the screen that will bring up the message for me.

Any help would be appreciated.

Thanks!

It's peculiar that the Open/Save/Cancel dialog, at least in my case, says it's an ASPX file without being more specific about the content-type. When I use a proxy to inspect the traffic, I see this:

Content-Type: application/x-java-jnlp-file; charset=utf-8

There were two other threads recently about JNLP file issues. I'm not sure either of them reached resolution, but for reference:
