Silverlight not working in Firefox 3.6.12

Viewed 892

We are having some wierd behavior in firefox with silverlight. We have tried everything and I am hoping for some more ideas. Below is the behavior

  1. Install firefox (3.6.12) and silverlight (4.0.50917.0). The versions there are locked and not controlled by us and on all our users machines.

  2. Visit our silverlight application (also tried simple application with just a background)

  3. Instead of seeing our application, you see "Get Microsoft Silverlight" -- (about:plugins reports silverlight 4.0.50917.0 installed and enabled)

  4. Visit site in IE, app works

  5. Install or uninstall any plug-in (tried Firebug and IETab2)
  6. After install, click "Restart" when prompted
  7. After FF restarts, silverlight works as expected
  8. Close firefox and reopen.
  9. Once again, silverlight is broken

Any ideas? We tried the CWDIllegalInDllSearch entry in the registry to no avail. Please help!
