Released in 1995, Java is a computer-like programming language and platform designed to shape programs, tools, and other solutions. Through this medium, many companies have developed software in recent years, focusing many resources on the web environment to provide the pages with a greater number of functions and types of content.
With an increasingly reduced use by more modern standards such as HTML5 and others, Java is used to display multimedia content on a website . It allows the reproduction of videos through players, as well as executing other tasks that serve to view images or even listen to music, in addition to starting small programs within an online portal. Compatible with most browsers, it was and is something that allows websites to be given greater flexibility.
At the user level it is important to have it installed and updated to ensure the best possible compatibility with websites. In case you have problems and do not know how to enable or disable Java in the Mozilla Firefox browser, we are going to help you with this guide. We explain what to do step by step, but we also warn you that there are fewer and fewer supported browsers.
Steps to allow or disable Java in Firefox browser
Currently, the new Firefox update does not support Java . Since the release of version 52, it is not possible to see content used with this language when navigating with Mozilla’s proposal. If you have a version equal to that or earlier, we can give you the steps to allow or disable Java in the Firefox browser.
This is what you have to do:
- Open Mozilla Firefox on your computer as usual.
- Once loaded and you are inside, click on the “Menu” icon , which contains three horizontal lines and it’s in the upper-right corner of the window.
- Within the drop-down that appears at the moment, go to “Add-ons” and click on that section.
- Now you are inside the “Add-ons Manager” . Among the available options, you must go to “Extensions ” and click there.
- Look through all the available plugins until you find one called “JAVA (TM) Platform” . Click on it to enter its settings.
- Now, you can decide if you want it to be activated or deactivated . You just have to click on the button that appears with the corresponding text for it.
If you leave it activated, Firefox usually asks when you enter a website that has content that needs Java to function properly. You just have to go to the place where it should be and click on “Activate Java Platform …” .
* If when entering a website and you cannot find this, go to the red icon that is before the URL in the address bar and click on it, then click on “Activate Java ” and establish whether to allow once or forever for the website in question.
Java plugin not working in Firefox, solution
If the Java extension does not run correctly in Mozilla Firefox, it is possible that the problem comes from the plugin itself. In this case, the solution that can be put into practice is to review and update.
These are the steps to follow:
- Open the Mozilla web browser or any other that you usually use.
- When it loads, go to the address bar and enter the following URL to enter the Java downloads section: https://www.java.com/en/download/
- Once inside, click on the “Java free download” button .
- A compatibility warning message may appear. Ignore it and click on “Accept and start free download” to move forward.
- Once the file has finished downloading, go to the folder where it was downloaded and open it by double clicking on it.
- Click “Install” in the first window that now appears.
- After this, press “Accept” and continue if you are asked for information. Then let the installer copy the corresponding files.
- Close the installation window once it is finished.
- Restart the computer to apply all the modifications.
- Go back to Firefox and see if Java works. If not, go through all the steps explained in the previous section.
If, after doing this, you still have problems with Java, the problem may be with your version of Firefox . Since revision number 52 landed in 2017, the browser has been completely reducing support for this solution, preventing the execution of content that uses its programming language on websites.
In this case, it would be necessary to access and download an older version of Mozilla Firefox, although it poses significant security risks as it does not have the most modern patches and improvements. Being something that can endanger the data of the computer and the user himself when moving around the internet.
