What is WebGL and how to disable it.

 

What is WebGL and why it’s dangerous?

WebGL (Web-based Graphics Library) is a collection of code for JavaScript that makes it possible for a website to access your video card in order to display interactive 3D-graphics using the HTML5 Canvas element—without using any third-party plug-ins.

WebGL can be a threat to your device security and online anonymity.

 

How to be protected?

You can disable WebGL manually in the browser Settings, or with a special plugins (e.g., "Disable WebGL" for Chrome).

 

How to disable WebGL in Firefox:

1. Open the browser settings page. To do this, type in the address bar: about:config

2. In the search box, type in: webgl

3. Find line “webgl.disabled”. It has the “false” value. It is necessary to change it to “true”. To do this simply click twice on this line.

 

How to disable WebGL in Google Chrome:

1. Find the Chrome shortcut, right-click it and select “Properties”.

2. The Target line contains the path to the file that starts the browser. It should end in chrome.exe. After that .exe, add a space and a record: -disable-webgl

3. From now on Chrome will be launched from this shortcut with a disabled WebGL.
