Mozilla has officially released Firefox 69 for Windows, Mac, and Linux. This version comes with enhanced tracking protection enabled by default and Flash disabled by default. The browser is now blocking known third-party tracking cookies and cryptominers in its default mode of operation. Firefox will also no longer need to identify users of 32-bit versions of Firefox on 64-bit operating systems. Mac users also get improvements in the form of a better battery life and an updated download UI for the Mac Finder.
