Silverlight 2, Firefox 3 and Windows Vista problem...

We discovered another Silverlight 2 Firefox 3 compatibility issue today. Don't get me wrong, I'm a huge Silverlight fan and a huge Firefox fan, and will put it on record that the 2 work really well together contrary to what many others might say. None the less, small issues do creep up from time to time.

The Silverlight 2 app we are developing wasn't working on Firefox 3 on a test machine with Windows Vista Enterprise. It was working fine in IE7 on that machine, and the strange thing was it was working fine on a colleagues windows Vista machine in Firefox3 (therefore i was certain it was machine specific).

I uninstalled the Silverlight 2 Plugin (v2.0.31005.0) but still noticed it in the Firefox plugins. I uninstalled and reinstalled Firefox 3 but it was still there, strange as like i said I'd uninstalled the plugin.

To sort it out I uninstalled Firefox 3 again, and deleted the Mozilla Firefox folder in my program files folder, in order to make sure i get a fresh start. After reinstalling Firefox I noticed the Silverlight plugin was no longer showing which is what i wanted. than after a reinstall of the Silverlight 2 plugin, All was working.

Strange, but it seemed Firefox was getting confused if it had the plugin or not and that was causing the problem.
