Yesterday Mozilla released Firefox 70. The newest version of the most-popular fully open source browser expands on the Enhanced Tracking Protection we saw as an option in Firefox 69 and turns that protection on by default for all users. We already saw most of these new features in our Firefox 70 beta coverage, but since then, the features have been expanded upon and fine-tuned, and major new features have appeared or have been added in the Lockwise online password manager for users who have a Firefox cloud account.
