I am concerned about my privacy online and wanting to minimize tracking/reducing my fingerprint, I have disabled a WebGL.

CHANGE

According to https://ipleak.com/articles/what-is-webgl-and-how-to-disable Firefox steps are:


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

In the search box, type in: webgl

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.
