I have Lubuntu 13.04, and I use the Midori WebBrowser. I initially had a problem with the plugins, but later on, I could activate Flash and Java. I use the IcedTea browser plugin to view Java content. This works perfectly fine with Chromium, but it fails to load in Midori. Sometimes, it even says missing plugin for both Flash and Java. In reviews, I have seen it reported that Java works fine in Midori even with IcedTea.
It would be helpful if you could say what the problem is, and help me solve this problem.
EDIT: I have the latest version of java and flash. Also, the website I tested for java, is the java test page in the java website, and also minecraft.net . For flash, it is Youtube.
