Steps to enable or disable Java in the Firefox browser
Currently, the new Firefox update is not compatible with 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 take 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 it loads and you are inside, click on the “ Menu” icon , which contains three horizontal lines and is located 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.
- You are now inside the “Add-ons Manager” . Among the options available, you should go to “ Extensions ” and click there.
- Look through all the available plugins until you find one called “JAVA (TM) Platform” . Press 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 you should be and click on “Activate Java Platform …” .
* If when entering a website and you don’t find this, go to the red icon before the URL in the address bar and click on it, then click on “ Activate Java ” and set whether to allow once or forever for the web in question.
The Java plugin does not work in Firefox, solution
If the Java extension does not run correctly in Mozilla Firefox , the problem may come from the add-in 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 web browser of Mozilla or any other one you usually use.
- When loading, go to the address bar and enter the following URL to enter in the Java downloads section: https://www.java.com/download/
- Once inside, press the button “Free download of Java. ”
- A warning message about compatibility may appear. Ignore it and click on “Accept and start free download” to move forward.
- Once you have finished downloading the file, go to the folder where it was downloaded and open it by double clicking on it.
- Press “Install” in the First window that appears now.
- After this, press “Accept” and proceed if you are asked for information. Then, let the installer copy the corresponding files.
- Close the installation window once finished.
- Restart the computer to apply all the modifications.
- Go back to Firefox and see if Java works. If not, review all the steps explained in the previous section.
If, after doing this, you still have problems with Java, the problem may be in your version of Firefox . Since the revision number 52 landed in 2017 , the browser has been subtracting the support completely from this solution, preventing the execution of content that uses its programming language on websites.
In this case, it would be necessary to access an older version of Mozilla Firefox and download it , although it entails significant security risks by not having any more patches and improvements Modern Being something that can jeopardize the data of the computer and the user himself when moving around the internet.
