This option is in the middle of the Settings window. Check the "Enable JavaScript" box.

It's next to the "Web content: Doing so enables JavaScript in Safari, though you'll most likely need to refresh your browser before affected pages will work. If there's a checkmark in this box, JavaScript is already enabled in Safari. Method 3. Open Firefox. It's a blue globe with an orange fox on it. By default, Firefox enables JavaScript and prevents you from changing this setting, but some applications interfere with the JavaScript implementation. This option is in the top-right side of the Firefox window. Click Add-ons. It's a puzzle piece-shaped icon in the drop-down menu.

Look for a JavaScript-blocking extension. Disable any JavaScript-blocking extensions. Click the problem extension and then click Disable or Remove when prompted. You'll have to restart Firefox for your changes to take place. Enable JavaScript through the advanced user settings. If disabling the JavaScript-blocking extensions didn't fix your problem, you may need to enable JavaScript from within Firefox's hidden settings: Enter about: Click I accept the risk!

Type javascript. Make sure the "Value" section of the javascript. If it says "true", JavaScript is enabled. Delete and reinstall Firefox. Double-click javascript. Restart Firefox. Reinstall Firefox. If all else fails, uninstall and reinstall Firefox to restore all of the default settings. Because JavaScript is a foundation of the Firefox browser, reinstalling should restore its functionality.

How To Pause Your Code With Breakpoints In Chrome DevTools

Click Custom level. This problem was observed on some Windows 7 systems when VPN software is used. This can be resolved by explicitly passing a parameter to the JVM:. For modern browsers which support tabs, each tab might be a separate browser process. If a Java applet is embedded in a browser page and the next generation plugin is being used, usually the process associated with the browser tab creates a JVM within the process browser VM.

The client VM is a Java process java. If your applet does not start, make sure to enable tracing and the Java console as explained previously. Then use hits below to find reason why applet does not work:. It is the same crash report file as for standalone applications.

Use Appendix B to read it. Note that if you can spot native libraries loaded from the deployment cache directory, especially if you see code from these libraries in the crash stack, it is very likely to be bug in the application. Otherwise it is a JRE bug and needs to be reported to bugs. To get more details about a JVM running in the browser process, set the following two environment variables before starting the browser:. On Windows, there should be a command window associated with the browser process. All browser VM debug output goes into the command window.

Check to see if any exceptions are visible there. A Java thread dump can be obtained by using the "Ctrl-Break" key sequence on the command window. On Linux and Solaris platforms, after setting the above variables, start the browser from the same session. All browser VM debug output goes into the terminal window. There are "heartbeat" messages sent between the client VM and browser VM. This will help isolate whether the problem is "heartbeat" related. If the log is not opening and environment variables are set in the browser process, then it is likely that the JRE is not installed correctly or Java is disabled.

Check for configuration errors and try to reinstall the JRE if nothing else helps. Note that the same client JVM may be shared between multiple applets. Sometimes intermittent failures happen because the shared JVM does not have enough resources available for example, heap size. In that case, a page reload often helps to resolve the problem. If application fails with an out of memory error, the heap size needs to be increased.

If an application is signed and the user declined a security dialog, this may cause application failure. The decision made by the user is remembered until the JVM is restarted. To see the security dialog again, the user may need to restart the browser. Note that applet can be deployed to reduce the risk of being affected by other applets and tailor execution environment for the applet's needs.

If page appears to be frozen while an applet starts, or in the runtime, the cause could be Liveconnect calls. On startup, an attempt to access Java applet from Javascript may block the Javascript engine until applet initialization is complete. It is recommended to postpone Javascript access until the applet is ready and use the enableStatusEvents parameter to unlock non-blocking access to applet status checks. To use Liveconnect in runtime, it is recommended to make Javascript calls return quickly to avoid blocking the single-threaded Javascript engine.

Note that jstack may highlight a deadlock if it happens in context of one of these VMs, but it cannot do this if the deadlock involves both processes. In this case, the thread stacks need to be examined manually. The Java Runtime will automatically warn the user about possible security sensitive issues. If you are confident that applications you use are safe, then it is possible to bypass security dialogs to simplify user experience.

This will result in security dialog box popup again in the future. Signed Java Web Start applications and applets that contain signed and unsigned components could potentially be unsafe unless the mixed code was intended by the application vendor. The latest versions of the Java runtime raise a mixed code warning dialog when a program contains both signed and unsigned components and suspicious use is detected. Bypassing this dialog generally requires making changes to application implementation or repackaging the application. It is also possible to completely disable the software from checking for mixing trusted and untrusted code, but it is not recommended as this allows the user to run potentially unsafe code with no warning and without additional protections.

For details on mixed code and ways to bypass this security warning dialog box, please refer to Mixing Signed and Unsigned Code — Ensuring Application and Applet Security. For Java Web Start applications and applets, you can use most of techniques available to debug and profile standalone applications, except you will need to use the "attach" mechanism instead of direct launch.

Note that both plugin and Java Web Start will spawn adidtional java or javaw processes that will actually run the JVM executing the application or applet. You need to attach to those processes to be able to collect info about your app. For example, if you want to get a memory dump of your applet, then first you need to figure out the process id for the java process executing the PluginMain class. For example, use the jps utility from the JDK and then use jmap to get a memory dump. For example, here is how you can pass details to the Java Web Start application from command line:.

This instructs the agent to suspend after the JVM is initialized and wait for a debugger to connect on port Please consult this guide for a full description of invocation options. See section 7. Now launch your browser. The NetBeans profile agent is enabled for any applet you will be running in this browser session.

Please consult your profiler documentation for exact details on what agent to use and how to configure it. Use any techniques available for standalone applications on the process running your applet or application. Use the jps utility to find the process id for the process running your application.
