How to allow Java on trusted sites
Firefox has stopped the Java plugin from running automatically because of security issues. However, you can still activate Java on trusted sites. We'll show you how.
- If websites report that the Java plugin is not installed, can't be detected, or is disabled in the browser, you won't be able to activate Java. See Use the Java plugin to view interactive content on websites for help installing, updating, and enabling Java in Firefox.
Activate Java once
When you see the "Activate Java" message, simply click it to load the Java content normally.
If there is no visible area to activate Java content in the webpage or if clicking on the "Activate Java" message doesn't work, look for the plugin icon in the address bar. Click on it and, in the message panel that opens, chooseto enable Java content temporarily.
Always activate Java for a site
If you have a trusted site that uses Java and you need to use that site often, you can make Java work normally on just that website.
- Click the plugin icon in the address bar and a message panel will open.
- In the message panel, click .
Now, whenever you visit this site, the plugin will automatically run and you won't get the "Click to activate" message.
Java security prompts
After activating Java for a site you may see a security prompt, asking you to confirm that you want to run Java, or a message such as "Application Blocked by Security Settings", with no option to run Java. These security prompts and messages come from Java itself, not from Firefox, and depend on the website and your security settings in the Java Control Panel.
