I used to have Firefox 18.0.1. Now have Firefox 19.0.2. I use a website where Silverlight 4 is required. Silverlight 5 is incompatible with the website. Firefox 18 allowed use of Silverlight 4. Firefox 19 has disabled the plugin as outdated. How can I force acceptance of Silverlight 4?

Your plugins list shows a Silverlight 4 version (4.0.60831.0), so I'm not sure why you are asking this.

Do you get an icon that plugins are blocked on the location bar or only on the web page at the position where the plugin should be?

Have you tried uninstalling the current version of Silverlight and installing version 4? What happens when you try to install version 4? What is the error message you are receiving?

Thanks for the response but cor-el's response has got me in.

I have been activating the Silverlight 4 plugin on each access attempt which resulted in a black screen. Your first link showed me an option I had not noticed before 'Always activate plugins for this site'. Using this has got me into the website. Thanks.
