Doug likes to visit the Aviation Weather Service online, but he's been having trouble with it lately. Leo says that's because it uses Java and the Java browser plugin has probably been disabled. Doug should go into his browser settings and be sure it's installed, updated, and enabled. But it's getting harder to use Java in the browser. If he has Firefox version 52 or higher, or Chrome 42 or higher, or even Safari, the plugin would have been disabled for security reasons. So his only choice may be to use Internet Explorer for that site. He'll have to turn on scripting for Java apps.
