How to Install Permissions for a Firefox Applet

Tweak Firefox settings to enable Java Applets.

The Firefox Web browser supports a wide range of programs and scripts used to provide dynamic or interactive features on websites, including Java Applets. Java support is usually enabled by default, but you may have disabled the option when upgrading the browser or changing the Web browser's security settings. To grant permissions to Java Applet programs in Firefox, access the browser’s add-on manager and enable the Java plug-ins.

Instructions

1. Launch Firefox. Click “Tools” in the main navigation menu at the top of the browser window.

2. Select “Add-Ons” from the drop-down context menu to open the Add-Ons Manager page.

3. Click the “Plug-Ins” tab in the left-hand menu. Firefox displays a list of all plug-ins in the main pane of the browser window.

4. Scroll through the list of installed plug-ins to locate the Java plug-ins.

5. Click the “Enable” button beside both the “Java Platform” and “Java Development Toolkit” plug-ins. Firefox saves and implements your changes automatically.

Tips & Warnings

• For versions of Firefox older than Firefox 3.6, click “Tools” followed by “Options” and “Content.” Click the “Enable Java” check box in the list of content options.

• Enable automatic updates for Java and other plug-ins by clicking the “Settings” button with the gears icon at the top of the Add-Ons Manager page. Select “Update Add-Ons Automatically” from the pull-down menu.
