I run Trisquel and recently switched to IceCat from the default browser because I wanted HTML 5 support. The only issue I have is that Java applets don't work, which they did in Trisquel's default unbranded Firefox browser. When ever I try to run a Java test app (such as http://browserspy.dk/java.php) I get a error and a dialogue box telling me to install "the Plugin." Clicking OK takes me to http://java.com/en/download/index.jsp. Isn't Sun MS's Java partially non-free? If so then shouldn't IceCat tell me to install a fully free plugin like it does with Flash?
