I'd check Tools -> Add-ons to see whether the WPF plug-in for Firefox is both installed and enabled. If it isn't installed then you download and copy it to your Firefox plug-in directory - C:\Program Files(x86)\Mozilla Firefox\plugins is the default location for Windows 7 - from this link: https://sites.google.com/site/npwpfplugin/

After reading through that blog, I came across this link to part 2: http://blogs.microsoft.co.il/maxim/2008/03/31/how-to-run-wpf-xbap-application-in-full-trust-mode-post-2-certificate-extraction/ There's a comment at the end of that blog where some-one says: "I am successfully able to install certificate on IE. But I am not able to install on FireFox. Can anybody help me out?" The author of the blog then replies: "Try this in FF: Tools [Menu] > Options [Sub Menu] > Advanced [Top Tab] > Encryption [Tab] > View Certificates [BTN] > Your certificates [Tab] > Import [BTN] > Select Certificate File and Import." So, if you've successfully installed the certificate for IE, I'd see if you can import it into FF as well.
