Does my browser support java applets

Does Firefox 50.1.0 support Java applets?

i have old Java applet started on my page. It worked in FF until its last update. In previous version, the warning was displayed before starting this applet, but now it’s not working. The popup is displayed: «Java Plug-in is not supported by this browser. . How to turn JAVA applets on in newest FF?

«Old Java applet» — be aware that JDK 9 will deprecate applets. It’s time to start thinking about moving off that tired technology. It’s 1995 vintage.

«almost» — there’s your problem. You won’t be able to wait another 20 years. FF and other browsers will decide for you.

I don’t think Java is gone completely in Firefox 50, but it will be going away for good in Firefox 52. Similar things are happening with Chrome. So the sooner you move away from applets the better, really.

it was application I took over from other developer, but I have ready solution but it’s «under review» now. Anyway thanks.

1 Answer 1

Yes, Firefox 50.1.0 supports Java applets. The problem is Java no longer supports Java applets because they are deemed a «security risk».
If you really want to run a Java applet in a browser, you will need to add it to the «Exception Site List» under the Security tab of the Java Control Panel. Also, the checkbox labeled «Enable Java content in the browser» will need to be checked.

Web Browsers that support Java Applets and how to enable them

Welcome to this comprehensive guide on web browsers that support Java applets and how to enable them. As one of the oldest technologies used for adding interactive content to web pages, Java applets are still occasionally encountered, even though the technology is considered outdated and many modern browsers no longer support it. This article aims to provide you with an understanding of how Java applets work with various web browsers and how to enable them.

Understanding Java Applets

Java applets are small applications written in the Java programming language and embedded in a web page. The primary purpose of a Java applet is to provide interactive features on a web page that cannot be provided with HTML alone. These applets run in the context of the web browser, under the control of the Java Virtual Machine (JVM), offering functionalities like computations and real-time data updates

Web Browsers That Support Java Applets

As of my knowledge cutoff in September 2021, most mainstream browsers, including Google Chrome, Mozilla Firefox, Safari, and Microsoft Edge, no longer support Java applets due to security reasons and the fact that more modern and secure technologies have replaced the need for Java applets.

However, the Internet Explorer 11, the last version of Internet Explorer that was discontinued in 2021, still supports Java applets. Also, some other older or less commonly used browsers might still offer Java applet support.

It’s crucial to note that running Java applets may pose security risks, as applets can have the same permissions as native software installed on your system if not properly sandboxed. Therefore, the use of Java applets is generally discouraged

Enabling Java Applets

While most modern browsers have discontinued support for Java applets, if you have an application that still requires Java applets, you can enable it on Internet Explorer 11 or any other older browser that supports Java applets

Please note that this is generally not recommended due to the security risks associated with Java applets. If you decide to proceed, do so with caution.

Step 1 − Install or Verify Java Installation

To run Java applets, you must have the Java Runtime Environment (JRE) installed on your computer. You can check if Java is installed by opening the command prompt and typing java -version. If Java is installed, it will show the installed version. If not, you’ll need to download and install the Java Runtime Environment from the Oracle website.

Step 2 − Enable Java through the Java Control Panel

Once Java is installed, go to the Java Control Panel. You can find it in the Windows control panel or search for ‘Java’ in the start menu.

In the Java Control Panel, select the ‘Security’ tab, where you’ll find the ‘Enable Java content in the browser’ checkbox. Ensure this box is checked and set the security level to ‘High’ or ‘Very High’ to enforce strict permissions.

Step 3 − Configure Internet Explorer

Open Internet Explorer and go to the ‘Tools’ menu. Select ‘Internet Options’, then the ‘Security’ tab. Click on ‘Custom Level’, scroll down to ‘Scripting of Java applets’, and make sure ‘Enable’ is selected.

Remember to restart your browser after these changes

Conclusion

Java applets were once a popular choice for providing interactive content on web pages. However, with the rise of new technologies like JavaScript, HTML5, and CSS3, Java applets have been phased out due to security concerns and compatibility issues

While it’s still possible to enable Java applets in some older browsers, it’s generally not recommended due to the potential security risks. Modern, secure, and more efficient technologies should be considered for providing interactive web content

It’s also worth mentioning that developers and organizations should consider upgrading or refactoring applications that still rely on Java applets. There are numerous modern alternatives, such as JavaScript, HTML5, CSS3, and various web application frameworks that offer the same capabilities as Java applets, with better security, performance, and compatibility with modern web standards and browsers.

Overall, while Java applets hold an important place in the history of web development, their usage in today’s web environment is not recommended. If you’re a developer or a business still using Java applets, it’s time to look into modern, secure, and efficient alternatives for your web applications. If you’re a user trying to access content that requires Java applets, be aware of the security risks involved and consider using a dedicated machine or a virtual machine to isolate potential security threats.

Web Browsers that support Java Applets and how to enable them

This article is about the support of Java on browsers.

Why we need the support of Java on a browser?

If you learned or have some knowledge or have worked in Java then it is likely that you must have come across this concept of Java Applet. So, an Applet is nothing but a Java program but the only difference is that it cannot directly run on a standalone machine. It needs a web browser to run. It is easily embedded within an HTML page and is a client-side concept i.e. runs on client-side.

So, to run Applet, we need a Java-enabled browser. Browsers come with a Java plugin that allows the execution of an Applet on it. And so, the browsers that come to Java enabled, can run Applet without any hassle.

So, now that we know why we need browser support for Java, let’s start with the list of browsers that support it today.

Browser that supports Java:
Browsers require Java plugin which depends on NPAPI (Netscape Plugin Application Programming Interface). Today, the majority of the well-known browsers have dropped the support for that.

Here are browsers that do not support Java Applet any more:

So, as you can see that all these browsers not longer support Applet. Even the newer versions of Oracle’s JDK does not come with the support of the Java browser plugin.

The reason for dropping the support was because of security issues and risks that were found.

But there is Internet Explorer that still has the support for Java Applet. So, today Internet Explorer is the only browser that supports Java Applet.

How to enable Java in Internet Explorer?
Following are the steps to enable Java on Internet Explorer:

1. Click on the ‘Tools’ icon on the top right corner of the window or press Alt+X, if on windows.
2. Then for the menu select ‘Internet Options’.
   
3. Then in ‘Security’ tab, click on ‘Custom level’.
   
4. Now, In the pop-up, scroll down and search for ‘Scripting of Java applet’ and make sure it is enabled and click OK.

Note: There is another way if you still want to run Applet and security is not a concern and if you don’t want to use Internet Explorer, then you download an older version of any browser that did support Java Applet.
