70.0
Firefox Release

October 22, 2019

Version 70.0, first offered to Release channel users on October 22, 2019

Enhanced Tracking Protection (ETP) is on by default on all platforms bringing privacy protections to all our users. With this release, you can now see the many ways ETP protects you in a Privacy Protections report.

We'd like to extend a special thank you to all of the new Mozillians who contributed to this release of Firefox.
