Java Plugin 1.6 Causing a Firefox Crash
Java is a programming language that several websites require to perform tasks such as playing games, chatting or viewing images. In Firefox, Java 1.6 will often crash the browser and cause it to close unexpectedly if the Java program is corrupt or incompatible with the browser. If Java 1.6 isn't performing on Firefox as expected, review these common solutions to improve performance.

Causes of the Crash
-
Java 1.6 is an older version of the programming language, and primarily used with Windows Vista and prior Windows operating systems. If Java 1.6 is unable to execute when you visit Java-intensive pages, the browser crashes and closes unexpectedly. This problem is likely to occur when the program is damaged or corrupt, or if the Java-intensive pages or components require a newer version of the programming language.
Update
-
Installing the latest version of Java decreases the chances of freezing and crashing. Before installing a newer version, uninstall the old copy to lessen the risk of conflicts, especially if the currently installed copy is corrupt. After uninstalling the outdated copy, download and install a new copy from the Oracle website. Follow the setup wizard to install the program properly. When the installation process completes, restart Firefox for the changes to take effect.

Firefox Update
-
If you're using an older version of Firefox, an updated copy of Java may not perform as well as it should because of compatibility issues. Installing the latest version of Firefox to go along with the updated version of Java decreases the risk of crashing when you load Java-intensive pages.
Tips
-
Antivirus programs and firewalls may cause Java 1.6 to crash Firefox when you load Java-intensive pages. To verify whether the security program is problematic, temporarily disable it. If the problem goes away, refer to your security program's documentation for information on adjusting settings to allow Java communication.
