Mozilla is testing a new feature in its Firefox web browser that will grant users the ability to block Canvas fingerprinting. The browser will now explicitly ask user permission if any website or service attempts to use HTML5 Canvas Image Data in Firefox. The feature would be made available for every Firefox user from January 2018. Firefox 58 will also remove the controversial WoSign and its subsidiary StartCom root certificates from Mozilla’s root store, according to a discussion on the Firefox bug tracking forum. Mozilla already stopped allowing websites to access the Battery Status API and the information about the user’s device.
