Updated on March 15 to add that through an update to the NoScript extension (v11.0.17), this issue has been fixed. Original article below.

The Tor Project warned users yesterday about a major bug in its browser that may execute JavaScript code on sites that users have specifically blocked JavaScript from running.

Tor developers said they are working on a fix; however, they did not provide a timeline for a patch.

The ability to block JavaScript code execution is a crucial security feature of the Tor Browser Bundle (TBB), a browser with enhanced privacy-preserving features that also masks real IP addresses (locations) to keep users anonymous online.

Because of these features, the browser is often used by journalists, political activities, and dissidents in oppressive countries, as a way to skirt firewalls and online censorship.

In the past, there have been exploits that used JavaScript code to unmask a Tor Browser user's real IP address. Some have been used to target and unmask criminal activities [1, 2], while others were used in mysterious circumstances [1, 2].

Yesterday, the Tor team said they found a bug in TBB's security options. When the browser was configured to use the highest security level (called "Safest"), it still allowed JavaScript code to execute, even if it should have blocked it.

"We are aware of a bug that allows JavaScript execution on the Safest security level (in some situations)," the Tor team said.

"We are working on a fix for this. If you require that JavaScript is blocked, then you may completely disable it."

To completely disable JavaScript execution in the Tor Browser, the Tor team provided the following instructions:

  • Open about:config
  • Search for: javascript.enabled
  • If the "Value" column says "false", then JavaScript is already disabled.
  • If the "Value" column says "true", then either right-click and select "Toggle" such that it is now disabled or double-click on the row and it will be disabled.

Javascript was first introduced in 1995 and it is one of the most popular computer programming languages that is lightweight and dynamic. Lightweight means easy to implement as well as minimalist features and syntax. JavaScript is used to create web applications or web pages and is used by 95 percent of websites in the world. JavaScript is so popular because of its simple and intuitive syntax as well as being easily implementable and supported by HTML.

Tor is a browser that is getting popular day by day and was originally developed in the mid-1990s for the purpose of communicating in an anonymous and secure manner. Nowadays, people use it for exactly the same reason ie to keep their privacy and anonymity on the browser.

Tor is also called an Onion router. With Tor, we can browse the internet anonymously as it involves a number of volunteer relays that ensure the bouncing of internet traffic and guarantee that the user browsing is not monitored.

Why is it important to disable JavaScript?

It is important to disable JavaScript in Tor for many security reasons as the Tor browser’s earlier versions were vulnerable to JavaScript attacks because JavaScript provides a backdoor to the hacker or attacker from which the attacker can track the user using the user’s provided session details. It happened back in 2013 where hackers took advantage of the Noscript feature being disabled in the Tor browser and extracted users IP addresses and Mac addresses.

Now that we know why disabling JavaScript is important let us continue and go through all the steps to actually achieve our purpose of disabling JavaScript in the Tor browser:
