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.
More privacy protections from Enhanced Tracking Protection:
Integrated breach alerts from Firefox Monitor, to alert you when saved logins and passwords are compromised in online data breaches.
Complex password generation, to help you create and save strong passwords for new online accounts.
Improvements to core engine components, for better browsing on more sites
large codebases and improve page load performance by as much as 8
WebRender rolled out to more Firefox for Windows users, now available by default on Windows desktops with integrated Intel graphics cards and resolution of 1920x1200 or less, for improved graphics rendering.
The Developer Tools Accessibility panel now includes an audit for keyboard accessibility and a color deficiency simulator for systems with WebRender enabled
Inactive CSS: The Inspector now grays out CSS declarations that don’t affect the selected element and shows a tooltip explaining why -- and even how to fix it.
The new DOM Mutation Breakpoints in Developer Tools allows developers to diagnose when scripts add, remove or update page content. This makes debugging of complex script interactions and dependencies a lot easier.
WebExtensions developers can now inspect browser.storage.local data using the "Addon Debugging" Firefox Developer Tools.
With new network resource search in Developer Tools, you can quickly find resources based on their request and response data, including headers, cookies and content.
