Above all, JavaScript is the leader, a scripting language that is supported by all common browsers. And although it is an integral part of almost all modern web projects, JavaScript is not only known for positive headlines and is being blocked by some applications and even more and more users.

However, the options for the various Internet browsers are in different places. So we’re going to show you how to find the right options for Javascript in your browser and how to enable or disable it.

How to enable JavaScript in Chrome

In the Google Chrome browser, there are two ways to navigate to the Javascript settings. Open a new window or tab and enter chrome: // settings / content / javascript in the address bar . This will take you to the correct settings immediately and click the slider for “Blocked” so that Javascript is activated (“Allowed”) for Google Chrome. The change is applied immediately without having to restart the browser.

Alternatively, you can manually navigate to the appropriate settings. To do this, click on the button with the three dots to the right of the URL bar and select “Settings”. Then scroll down to the bottom of the page. Under “Advanced” you need to navigate to “Security & Privacy” and click the “Content Settings” button. There the button “Javascript” is listed, where you can activate Javascript as described above.

Chrome content settings

In the content settings of Chrome, not only JavaScript can be activated: The menu deals with a wide variety of content types and the question of whether these can be displayed by the websites accessed.
In the last step, select the programming language from the list of content types and move the slider for ” Allowed (recommended) ” to the right. Since Chrome automatically applies the changes, you have successfully activated JavaScript.

How to enable JavaScript in Safari / how to enable JavaScript on iPhone

If Apple Safari is the browser of your choice, for example when surfing with a Mac or iPhone, you also have the option of turning JavaScript off or on again manually. To do this, click on ” Safari ” in the macOS menu bar (requires that the browser has been started beforehand) and then select the ” Settings ” entry .

Another click loads the video from YouTube. In this case, YouTube can set cookies over which we have no influence.

You will find the settings for web content under the item ” Security “, which is marked with the lock symbol. To activate JavaScript in Safari, Put a tick in the checkbox of “Activate Javascript” and close the window.

How to enable JavaScript in Firefox

To activate JavaScript in Firefox, it is necessary to open the hidden configuration menu of the Internet browser. In addition to the standard customization options, there are various, in some cases still experimental, options that ordinary browser users do not have to deal with. You can call up this extra menu by entering ” about: config ” in the address bar.

If you start this menu for the first time, Firefox reacts with a warning message abut the warranty… Firefox informs you that all changes made can affect the stability, security and performance of the browser.The message only disappears after you click on “I am aware of the dangers!“.

The “about: config” area has its own search function (directly below the address line), which you can use to find the entry for JavaScript in the next step. Enter the following search term: javascript.enabled

Firefox then lists the entry of the same name for which the value “false” is entered if the programming language is deactivated. Double-click on the line if you want to reactivate JavaScript in your Firefox. Instead of the value “false”, the value “ true ” should now be displayed.

For the entry javascript.enabled in Firefox there are only the two values ​​”true” (JavaScript is activated) and “false” (JavaScript is deactivated).

JavaScript is also activated by default in Opera. Should the programming language be switched off for certain reasons, you can undo this as follows: Open the menu via the Opera icon and click on the ” Settings ” button . On the left side you will now find the menu item “ Websites ”, which you can select with a simple left click. Finally, look for the entry that is overwritten with “JavaScript” and change the selection to ” All websites are allowed to run JavaScript (recommended) “.

Opera configuration: “Websites”

Anyone who has activated or deactivated JavaScript in Opera via the settings can exclude individual websites from the selection made using “Manage exceptions”.

How to enable JavaScript in Internet Explorer

If you still use a version of Internet Explorer for your visit to the World Wide Web, you also have the option of turning JavaScript on or off. The corresponding setting can be found in the ” Internet options “, which you can open by clicking on the gear symbol .

To activate Javascript in Internet Explorer, first click on the cogwheel to the right of the URL bar. Alternatively, you can open “Extras” in the menu bar. Now select the item “Internet Options”. A new window will open in which you must select the “Security” tab. Different zones are listed here. After you have selected the “Internet” zone, click on the “Adjust level” button. In the new window scroll down to “Scripting” and set “Active Scripting” to “Activate”. The opened windows for the Internet options must be closed with the “OK” button, because only then will the customized options for Internet Explorer be adopted. Confirm the warning with “Yes”.

Alternatively, you can click on the “Standard Level” button after selecting the zone, because “Active Scripting” is automatically set to “Activate”. Note, however, that all other adjustments in the zone are also reset to the default value.

Security settings in Internet Explorer

For each selected zone, pre-defined security levels can be selected in Internet Explorer, which you can revise as required using “Adjust level”.
Look for the entry ” Active Scripting ” (under the category “Scripting”) and mark the item “Activate” to activate JavaScript in Internet Explorer. If you then confirm the change with the “OK” button, the browser will respond with the question whether you really want to accept the settings, which you confirm.

Internet Explorer: Adjusting the security level for the “Internet” zone
JavaScript can not only be activated or deactivated in Internet Explorer – by selecting the “Confirm” option, you decide manually for each website you visit whether the programming language should be allowed or not.

Note: Most versions of Internet Explorer have not been updated by Microsoft since January 12, 2016 . Only Internet Explorer 11 is still receiving support from the American company in the form of minor security updates. In order not to unnecessarily endanger the protection of your browser and your data, you should consider switching to the successor Edge or to another browser.

How to enable JavaScript in Microsoft Edge

In the Microsoft Edge browser, there is no way to adjust the options for Javascript, because there is no need to. Javascript is activated in this browser by default. However, this means users of Windows 10 and Microsoft Edge have to deal with two special features when it comes to deactivating or reactivating JavaScript.

On the one hand, owners of the Home and Starter editions have no way of updating scripts in the programming language Switch on the Microsoft browser. On the other hand, the configuration for all other users works exclusively via the system settings (group policy management) and not via the browser itself. The following steps are necessary for this:

  2. Start the suggested editor for managing the group policies with a double click.
  3. Select the “Administrative Templates” area and then “ Windows Components ”.
