With the release of Firefox 57 in 2017, Mozilla rebranded its open-source browser as Firefox Quantum and outlined ambitions to take the fight to market leader Google. Since then, Mozilla has steadily changed the look and feel of Firefox, and added functions such as Firefox Send, Facebook Container, and Firefox Monitor.
With Firefox 67, Mozilla continues to bisect privacy and performance, with a focus on the latter. Mozilla is pumping the brakes on less common features, choosing to identify areas in which the browser could operate quicker.
