Best known for its Firefox web browser, the organization that traces its origins back to the Netscape products of the 1990s prides itself on its efforts to keep the internet "open and accessible to all." It's positioned Firefox as a privacy-focused alternative to Big Tech browsers like Google Chrome, Microsoft Edge, and Apple Safari. In 2017, it acquired the makers of Pocket, an app for finding and saving meaningful online content. In recent years, Mozilla has also worked on efforts to crowdsource an open and diverse dataset for training voice recognition systems. In 2018, it also launched tools to protect users from tracking code as they navigate the web, including software to cordon off Facebook from other browser activity.
