Everybody uses Web browsers and sooner or later you will need to run Java applets to be able to view some content. Java is one of the most used platforms – it’s used on the Internet, on laptops and datacenters, Java technologies are used by Amazon Kindle, cell phones, game consoles, and lots more.
Most of the time Java works well and Java applets run smoothly. However, sometimes Java freezes when you try to run an applet in your browser window. When Java freezes, it completely stops responding, freezes the browser and the user is forced to kill the browser process from the Task Manager. This Java error can occur no matter which browser you try to use – Firefox, Internet Explorer or Google Chrome.
If your Java keeps freezing and you keep getting the Java applets won’t run errors, follow these steps to fix the problem.
First of all, check if Java is enabled in your browser. If it’s disabled and you are trying to run Java applets, the applets won’t run. To enable Java in your browser, do the following:
- Click on Tools and then go to Internet Options
- Select the Security tab and click on the Custom Level button
- Scroll down to Scripting of Java applets
- Make sure the Enable radio button is selected
- Click OK
- Click on the Firefox button at the top of the window (or Tools menu in Windows XP), then click on Add-ons
- On the Add-ons Manager tab, select Plugins
- Click on Java (TM) Platform plugin
- Click on the Enable button (if the button says Disable, Java is already enabled)
- Restart Firefox
- Click on the wrench icon, then select Options.
- Select Under the Hood and then select Privacy Content Settings.
The Content Settings panel will appear.
- In the Plug-ins section, select the Disable individual plug-ins link and see whether Java is enabled
- If it’s disabled, click on the Enable link
If Java is enabled, but you still can’t run Java applets, you should make sure you have the latest version of Java. The best way to update Java is to uninstall the old version and install the latest update. To do that, go to the Control Panel – Programs – Uninstall a Program (Add or Remove a Program in XP), find Java and uninstall it. Reboot your computer and scan it with a registry cleaner to make sure all traces of the old version are removed. Then go to the Java website, download the latest version and install it.
This should fix Java freezes and fix the Java applets won’t run error.
