In a big allusion to privacy, new versions of Mozilla's Firefox web browser will by default prevent third-party vendors from tracking users' online behavior, Mozilla said Thursday.
Although many popular web browsers like Google (goog) Chrome and Microsoft's (msft) Internet Explorer include options for limiting the amount of data that companies can collect. Users must manually activate these settings. Mozilla, on the other hand, said that it would shut off the ability, which means that users will need to specifically re-enable it to track it.
Mozilla said in a blog post that "many of the drawbacks of unchecked data collection are completely obscure to users and experts," and then cited a message about Cambridge Analytica's Facebook scandal as an example of a privacy breach. Facebook (fb) was heavily criticized by lawmakers for failing to protect user data from the political consulting firm Cambridge Analytica, which received the Facebook data from an academic researcher who had collected it in violation of Facebook's lax policy [1
This spring during a congressional hearing on Facebook's recent privacy mishaps, New Jersey Rep. Frank Pallone asked Facebook CEO Mark Zuckerberg if the company would change its default privacy settings to minimize data collection. Zuckerberg responded without committing, saying that "this is a complex topic that deserves more than a one-word response."
Mozilla also said that his efforts to reduce data that third parties could collect via his browser would also combat data. This technique, according to Mozilla, enables companies to "invisibly identify users" about certain attributes and internal settings of their devices that people can not control.
The upcoming Firefox versions also prevent Web pages from automatically entering the computer's software code into the users' computers, which secretly derive computer resources to the cryptocurrency.
