How to disable Javascript in Safari, Chrome and Firefox browser

Along with HTML and CSS, JavaScript is one of three programming languages ​​that browsers can read natively. Under this condition, these languages ​​are the mainstay of almost all current web pages . However, for one reason or another you may want to disable the latter. Therefore, in this article we will show you how to disable JavaScript in your Safari, Chrome and Firefox browsers. But first, we will analyze the risks that this implies.

Keep this in mind before disabling JavaScript

JavaScript is a programming language that was born in 1995 and that, since then, has evolved and refined. Thanks to its great versatility, this language is used when creating web pages with Google Sites , WordPress, Draftium and many other platforms, which is why it has become one of the languages ​​most used by today’s webs .

In fact, according to an analysis by, 95% of the current pages use this language and many of them do not have an alternative version that works without these scripts.

This is why the execution of content in this language is activated by default in all browsers. If you want to disable it, whether for security or other reasons, keep in mind that the vast majority of the pages you visit will not show much of their content. What’s more, you probably wo n’t even be able to navigate properly through the webs .

How to disable JavaScript in your browser

With the above in mind, we will now teach you how to disable JavaScript in three of the most used browsers today. If you don’t want to make such an extreme decision, you can also install an extension for Chrome that helps you better control the scripts that the pages run. We recommend ScriptSafe. Anyway, if you want to disable JavaScript we will show you below.

Google Chrome

  1. Open Google Chrome.
  2. Click on the three dots (Plus) located in the upper right corner. Then select “Settings”.
  3. Scroll down to the “Privacy and Security” section and select the “Website Settings” option.
  4. Finally, in the “Content” section, click on the “JavaScript” option and press the blue button to deactivate it.

Another option is to block web pages in Google Chrome that you do not want any member of your family to access.

Mozilla Firefox

  1. After accessing the browser, select the icon of the three parallel bars (Menu) located in the upper right corner.
  2. Click on “Options”. Then click on “Content”.
  3. Uncheck the “Enable Javascript” box. If you wish, you can also access the “Advanced” menu to manipulate certain aspects of this type of content.
  4. Finally, close the configuration page to save the changes.

The above method will be the easiest to disable JavaScript . Now, if for one reason or another you could not access that panel, below we will show you a slightly more tangled route.

  1. In Firefox, go to the following page: “about: config”. If this is the first time you access it, you will get a warning. Uncheck the box so that the notice does not appear again and confirm that you accept the risks.
  2. In the search bar that appears, type “JavaScript.enabled” and press “Enter.”
  3. Right click on the result of the same name and select “Modify” or “Toggle”. Now JavaScript will be disabled, which you can confirm by looking at the word “Modified” in the “Status” column.
  4. If you wish to activate it again, repeat the same process and click “Modify”.

These are the two methods that exist to disable JavaScript in Firefox. With regard to the latter, we advise you not to manipulate any other option unless you know exactly what you are doing .

Apple safari

  1. Enter the browser and click on the “Preferences” option.
  2. Select “Security”.
  3. Uncheck the ” Allow JavaScript ” box.
  4. Close the configuration tab to save the changes.

And that’s how easy it is to disable all the content of the web pages programmed in this language, and if at any time it becomes necessary, you will only have to re- enable JavaScript in any Web browser. We hope this tutorial has helped you, not only to disable your browser’s JavaScript, but also to learn a little more about how web pages work.
