As we already mentioned in the article on how to clean your computer from viruses, when you visit untrustworthy sites, it can be very useful to disable javascript in your browser, thereby reducing the likelihood of your computer being infected by various viruses through these sites. There are also cases when your favorite site, for some reason unknown to you, displays an incomprehensible message “You have javascript disabled.” What is javascript and how to enable and disable it in today's popular browsers, we will tell you in this article.

Javascript is a programming language that adds interactivity to web pages. It is used to create beautiful pop-up menus, windows, tooltips and much more on the pages of modern websites. Since javascript is executed on the user's side (on his computer), and not on the server like other programming languages for the Web, it has become a tool in the hands of various attackers who, with its help, began to exploit the vulnerabilities of Windows operating systems to inject viruses onto user computers.
Despite the fact that javascript itself, due to the peculiarities of its operation, does not contain viruses in the usual sense, but with its help it turned out to be convenient to implement cyber attacks and run malicious code written in other programming languages. To avoid this, you can disable the execution of javascript in the browser you use on sites that you do not trust and enable it only for trusted sites. We will describe below how to do this in the well-known four browsers (Internet Explorer 9, Mozilla Firefox, Opera, Google Chrome). How to disable javascript in Internet Explorer 9.
Open your browser. Press Alt+X and go to Internet Options. In the window that opens, go to the “Security” tab. In the “Select a zone to configure its security settings” window, select “Internet” by left-clicking on it. The icon should be highlighted in blue. After that, click on the “Other...” button below. A window titled “Security Settings - Internet Zone” will open. In it, almost at the very bottom, find the “Scripts” section with the subsections “Active scripts” and “Run Java application scripts”. Set the switch to the “Disable” position. After this, javascripts in Internet Explorer 9 will not work.

How to disable javascript in Mozilla Firefox.
In the Mozilla Firefox browser, scripts are much easier to disable. To do this, in an open browser, click on the Firefox inscription in the orange background in the upper left corner, in the window that appears, select “Settings” and in another pop-up window also click on “Settings”. In the window that opens, go to the “Content” tab and uncheck the “Use javascript” checkbox. Click OK. Scripts are disabled.

How to disable javascript in Opera.

How to disable javascript in Google Chrome.
With your browser open, click on the wrench at the top right. Select the “Settings” menu item. In the left column, select the “Advanced” section, where at the very top click the “Content Settings...” button. In the third group from the top called “javascript”, check the box for “Prohibit execution of javascript on all sites”. Click on the gray cross in the upper right corner. Execution of javascripts in Google Chrome is disabled.

How to disable javascript in Safari.
Open Safari. In the upper right corner, click on the main browser settings menu in the form of a gear. In the menu that appears, select “Settings” and go to the “Security” tab. In this tab, uncheck the “Enable javascript” option and close the window. After this, JavaScript in the browser stops working.

Not all sites currently retain their full functionality when the user's javascript is disabled. Some completely lose their ability to work. In this case, the message “You have javascript disabled” will be displayed, which we talked about at the beginning of the article. But, knowing how to disable javascript, you can now easily enable their support back by following the appropriate steps.

Accordingly, most of the time you have to work with the browser. To make the possibilities of working in the program wider and all the content being viewed looks better, the developers are introducing some additional elements.

They support the third edition of the specification, and Mozilla Firefox even attempted to support the fourth edition. By default, JavaScript is used by default on almost all Internet browsers, and it is usually disabled by the user himself.

As for the use of the language, it is necessary, for example, in some web applications, scripts in browsers (we are talking about special programs that allow you to format pages, automatically fill out forms, hide part of the content, and so on), as well as in AJAX ( an approach to building application interfaces in which data exchange with the server occurs in the background, due to which the page is not completely reloaded, and the operation of the application itself only speeds up).

Modern websites are created using various elements that make them interactive, visual, convenient and beautiful. While a few years ago web pages were mostly text and images, almost any site now has a variety of animations, buttons, media players, and other elements. So that you can see all this in your browser, modules are responsible - small but very important programs written in programming languages. In particular, these are elements in JavaScript and Java. Despite the similarity of names, these are different languages, and they are responsible for different page details.

Sometimes users may experience some problems with the operation of JavaScript or Java. In this article you will learn how to enable JavaScript and install Java support in Yandex Browser.

JavaScript is responsible for displaying scripts on the page, which can have either an important or a minor function. By default, JS support is enabled in any browser, but it can be disabled for various reasons: accidentally by the user, as a result of crashes or due to viruses.

To enable JavaScript in Yandex Browser, do the following:

You can also instead "Allow JavaScript on all sites" choose "Exception Management" and assign your own black or white list where JavaScript will not or will not run.

Installing Java

For a browser to support Java, you must first install it on your computer. To do this, follow the link below and download the Java installer from the official website of the developers.

Installing the program is as simple as possible and boils down to the fact that you need to select an installation location and wait a little while for the software to be installed.

If you have already installed Java, check if the corresponding plugin is enabled in your browser. To do this, enter browser://plugins/ into the address bar of your browser and click Enter. Look in the list of plugins Java(TM) and click on the button "Turn on". Please note that such an item may not exist in the browser.

After you have enabled Java or JavaScript, restart your browser and check how the desired page works with the modules enabled. We do not recommend disabling them manually, as many sites will not display correctly.
