Extension!=Plugin, Firefox!=Gecko(Core) and which Silverlight plugin version number is used in your test ?

Comment 2

[Arnoud van Bers]

Sorry about that..(although didn't know that it was the core and not firefox)
I use Silverlight 3 beta

Comment 3

[Matthias Versen [:Matti]]

Do you see the plugin in about:plugins ?
Did you already tried http://support.mozilla.com/en-US/kb/Safe+Mode to be sure that it's not caused by an addon ?

With a default profile and the 20090514 Mac (OS X 10.5.7) build:
Only a blue gradient background loads. The actual contents is nowhere to be seen. I checked with Gecko 1.9.0.11pre builds to see what 'should' happen.

And it is _not_ an issue of bad/stupid browser detection.

Silverlight: Version: 2.0.40115.0

Confirmed with latest trunk on Windows XP that Silverlight is not working on http://silverlight.net/Showcase/
Regression range is http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=515054a2dc43&tochange=c7b717f0a404

It isn't that silverlight doesn't work at all, it is that it doesn't work with some silverlight instances that use npruntime for scripting. Specifically, load this:

http://www.microsoft.com/silverlight/

And you'll see the following error in the JS error console:

Error: Trying to set unsupported property on NPObject!

Copy/paste error in part 1 patch from bug 474157, easy fix. I'll make a test too.
