• How to enable java plugin. Why does Java not work and how to enable it in the browser? Is the plugin disabled

    If you use the Firefox browser, aka Mozilla, to surf the Internet, and periodically encounter a problem loading videos, images, or the absence of any reaction when you click on a button somewhere on the site, the mess may be caused by the Java display settings in your browser. you can find out in this article.

    What is "Java" and why your browser does not like it

    Java is one of the widespread web technologies today. It is based on the functioning of many sites and programs. Why is Java support not enabled in the browser? Firefox refuses to support Java automatically because it considers it vulnerable to viruses. In the future, Firefox plans to drop support for any plug-ins (tools for playing content) other than Adobe Flash altogether.

    But such a policy of Mozilla regarding Java does not mean at all that when you turn on the corresponding plug-in, a million malicious programs will immediately rush to your computer. Sometimes you need to enable Java in Firefox for site performance reasons. This can be done in several ways.

    Single instance of Java inclusion

    Let's say you surf the internet, find a video you're interested in, and want to watch it. You press the Play button, but instead of playing, the following screen is displayed:

    The only action you need to take is to click on the inscription. In addition, Firefox may prompt you to remember this site and always activate the Java plugin on it. If you trust this site, then confirm your choice in the dialog box (Allow and Remember - "Allow and remember").

    Also, sometimes app blocking comes from Java itself and not from Firefox. More modern versions of Java have a number of rather stringent requirements for running applications. If the developer is unknown, then most likely the ability to run a Java application will be blocked. Even if you decide to enable Java in Firefox manually by accessing the security settings and selecting the desired site or application as an exception, the browser will still consider them suspicious and display a warning about a potential threat.

    How to enable Java support in Firefox

    There is another way to get to activating Java support. First you need to get to the page with plugins (open the menu and select the "Add-ons" button or press the keyboard shortcut Ctrl-Shift-A). You will see a list of addons, among which we need to find the following:

    If this plugin is not in the list, use the search bar in the upper right corner. You can search by the word Java - the search will return several add-ons, from which you can choose the appropriate one, having previously studied what functions they are designed to perform.

    If all of the above steps did not help you enable Java in Firefox, you may need to completely update the application on your computer. To do this, you need to download the latest version from the developer's website and install it on your device. After that, try opening Firefox again and launching the problematic site or app. In the end, a capricious site can be opened in another browser and see how it behaves there.

    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 you click on buttons, etc. Or, for example, pictures are not shown, and instead of them the inscription appears: security vulnerabilities. Click here to enable the Java(TM) Platform SE 7 U plugin." All this is due to the work of the Java plugin, which is present in browsers.


    Some browsers have Java pre-installed, some have to download it separately. But even if this plugin is installed in your browser, it is not a guarantee that it works, because sometimes the Java plugin needs to be enabled.

    If you encounter any problems displaying web pages, check do you have the java plugin enabled. To make it easier for you to do this, I wrote a small script that checks the browser and displays the appropriate inscription. Here is the result of the analysis for your browser:

    Javascript is OFF in your web browser If it is written above that JavaScript is enabled, then everything is in order, otherwise it must be enabled. The procedure is slightly different for each browser, so let's focus on each of them.

    3) Click the "Content Settings" button
    4) In the "JavaScript" section, activate the item "Allow all sites to use JavaScript"

    2) In the menu that opens, select "Internet Options"

    4) Close the window

    Now you know not only how to check if JavaScript works in your browser (just open this article and read the result), but also how to enable Java in Firefox, Chrome, IE, Opera and Safari!

    The use of Java applets is considered potentially dangerous, as it allows you 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 an option to enable / disable permissions to execute applications of this kind.

    Instruction

  • In the Mozilla Firefox browser menu, expand the "Tools" section and select "Settings". In the settings panel that opens, select the "Content" tab and check the box next to "Use Java". Then click the "OK" button and the browser will remember the change you made to the settings.
  • In the Internet Explorer browser menu, expand the "Tools" section and select "Internet Options". The browser will open a settings window in which you need to go to the "Security" tab. In the "Security level for this zone" section, click the "Custom" button to open a separate window with a long list of security options. Scroll to the bottom of the list and in the "Scripts" section, find the "Script Java Applications" subsection. Check the box next to "Enable" and close the window by pressing the "OK" button. Close the browser settings window, and then restart the program - the changes will take effect only after that.
  • In the Safari browser menu, expand the "Edit" section and select the "Settings" item. In the browser settings management window, go to the "Security" tab and check the "Enable Java" checkbox in the "Web Content" section. In this browser, the settings window is closed by clicking on the cross in the upper right window - there is no dedicated button for this, as in other browsers.
  • In the Opera browser menu, expand the "Settings" section and click on the "General settings" item. You can also press CTRL+F12 instead. In the settings panel, go to the "Advanced" tab and select "Content" from the list on the left. In the latest versions of the browser, there is no separate setting for enabling the use of Java applets, it is combined with the corresponding setting for other plugins, so the checkbox "Enable plugins" must be checked. In earlier versions, the "Enable Java" checkbox was placed above the "Enable plugins" checkbox. Once checked, click the OK button.
