Mozilla, the nonprofit developer behind the popular Firefox browser, will no longer advertise on Facebook.

"Mozilla is pressing pause on our Facebook advertising," Chief Operating Officer Denelle Dixon wrote in a blog post on Wednesday. She explained that in examining the social media site's policies after the recent news of the Cambridge Analytica scandal, "we found that its current default settings leave access open to a lot of data -- particularly with respect to settings for third-party apps."
