How do you configure firefox to open an application without prompting the user?

Question

I've got a serverside app that send down a custom mime-type file "application/x-optibase".

Firefox prompt user user to save or open the file and if the user clicks open the correct application launches so I believe I have mimeType.rdf configured correctly

I've gone into about:config and set

browser.helperApps.neverAsk.openFile to application/x-optibase

and

browser.helpApps.alwaysAsk.force to false

According to the minimal documentation out there this should enable the application to automatically open when the user downloads the file but it doesn't seem to work.

Any ideas?

Thanks.

Those preferences are no longer looked at as of Firefox 3. You have to have the mimeTypes.rdf file setup correctly. Specifically, for your mime type, you want to set NC:alwaysAsk to false. See this page for more details.
