If the browser plays videos without problems, the sites are full of online applications and delight with various convenient functions - this means that the Java plugin is enabled and working normally. Java is used by most sites, so if they do not work correctly, you need to figure out how to enable support for this technology.
For Google Chrome: enter the command “about:plugins” in the browser’s address bar. In the list of plugins, find Java and check its status. If “Enable” is displayed, click on it. When the plugin is enabled, the message “Disable” appears on the screen. To avoid having to confirm that Java is enabled in the future, check the box next to “Always Allowed.” You may encounter a situation where Java is not installed at all. Then you can follow the link and check it by clicking on the corresponding line. If the service detects the absence of a Java plugin, you will be prompted to download and install it. After successful installation, a request to enable Java will appear in the browser window, or you will need to enable it in the manner described above. For Mozilla FireFox: call the browser menu (top right of the screen) and go to the “Add-ons” section. In the window that opens, go to the “Plugins” tab and find the Java (TM) Platform programs already installed in the list. Set the Java operation option to Always Enable. If Java is not in the list of plugins, you must first install it using the link. For Opera: since this browser already has built-in Java components, it is enabled simultaneously along with all plugins. To do this, in the “Settings” menu, find the “Websites” tab, then activate the “Launch automatically” item in the “Plugins” section. For Internet Explorer: in the browser menu item, which can be opened by clicking on the gear icon in the upper right corner of the screen or by pressing Alt+X, select “Internet Options”. Then find the “Security” tab and click on the “Other” button. An impressive list of parameters will appear, among which you need to find the item “Run Java application script” and enable it. For Yandex Browser: enabling Java is performed almost identically to this process in Chrome. Write "browser://plugins" in the address bar and press "Enter". A window will open with a list of installed plugins. If the Java plugin is disabled, the Enable command will be active and the font will be light. After enabling, check the box next to “Always allow” and close the settings window.Now you know not only how to enable Java support in your browser. If problems arise with other plugins, the algorithm of actions will be the same. Please note that Java and JavaScript are not the same thing, and support for the latter is enabled in a completely different way.
The use of Java applets is considered potentially dangerous, as it makes it possible to remotely perform certain operations on your computer. However, a considerable number of sites use Java applications downloaded to the user’s computer, so the settings of most browsers provide a function to enable/disable permissions to execute applications of this kind.

Java is a popular technology that powers many websites and computer programs. However, users using the Mozilla Firefox browser began to encounter the fact that Java content in the web browser was simply not displayed.
Mozilla has abandoned all NPAPI plugins in its Firefox browser except Adobe Flash, starting with version 52. These instructions only apply if you are using an outdated version of the browser.
To enable JavaScript in Mozilla Firefox once on a page where you want interactive Java content to play, click the button "Enable Java" , after which the browser will start displaying the content on the current web page.
If there is no message on the web page you open indicating that you can activate Java, or nothing happens after clicking the “Enable Java” button, then pay attention to the left area of the address bar, where there may be a miniature icon with a cube.
If such an icon is available, click on it once with the left mouse button. An additional menu will appear on the screen, which has two items:
- "Temporarily allow" – Activate Java content only on the current page. But if you reload the page, Java access will need to be granted again;
- "Allow and remember" – activation of Java on this page. After the page is reloaded, the Java content will still be available.
What to do if Java still doesn't show up?
If the above steps did not help display the Java content, then we can conclude that an outdated version of Java is installed on your computer, or this software is missing altogether.
To solve the problem, go to the menu "Control Panel" , set the viewing mode in the upper right corner "Small Icons" and then open the section "Programs and Features" .
In the list of installed programs, find Java, right-click on the software and select "Delete" . If the program is missing, then immediately proceed to the installation stage.
Once the uninstallation of Java is completed, you can proceed to install the latest version. To do this, download the installation file from the link at the end of the article and install the software on your computer.
Finally, all you have to do is restart Mozilla Firefox, and then try again to activate Java, as described earlier. You can check Java for functionality in Mozilla Firefox.
We hope these tips helped you troubleshoot Java performance issues in the Mozilla Firefox browser.
Many Internet users are often faced with the fact that the drop-down menu does not work on sites, videos do not play, nothing happens when buttons are pressed, etc. Or, for example, pictures are not shown, but instead the message appears: “This plugin contains security vulnerabilities.
