What's new in this version:

New:
- Added support for WebAssembly, an emerging standard that brings near-native performance to Web-based games, apps, and software libraries without the use of plugins
- Added automatic captive portal detection, for easier access to Wi-Fi hotspots. When accessing the Internet via a captive portal, Firefox will alert users and open the portal login page in a new tab
- Implemented the Strict Secure Cookies specification which forbids insecure HTTP sites from setting cookies with the "secure" attribute. In some cases, this will prevent an insecure site from setting a cookie with the same name as an existing "secure" cookie from the same base domain
- Added user warnings for non-secure HTTP pages with logins. Firefox now displays a “This connection is not secure” message when users click into the username and password fields on pages that don’t use HTTPS
- Enhanced Sync to allow users to send and open tabs from one device to another

Fixed:
- Various security fixes

Improved text input for third-party keyboard layouts on Windows. This will address some keyboard layouts that:
- have chained dead keys
- input two or more characters with a non-printable key or a dead key sequence
- input a character even when a dead key sequence failed to compose a character

Changed:
- Removed support for Netscape Plugin API (NPAPI) plugins other than Flash. Silverlight, Java, Acrobat and the like are no longer supported.
- Removed Battery Status API to reduce fingerprinting of users by trackers
- When not using Direct2D on Windows, Skia is used for content rendering
- Migrated Firefox users on Windows XP and Windows Vista operating systems to the extended support release (ESR) version of Firefox
- Display (but allow users to override) an “Untrusted Connection” error when encountering SHA-1 certificates that chain up to a root certificate included in Mozilla’s CA Certificate Program. (Note: Firefox continues to permit SHA-1 certificates that chain to manually imported root certificates.) Read more about the Mozilla Security Team’s plans to deprecate SHA-1
- Improved experience for downloads:
- Notification in the toolbar when a download fails
- Quick access to five most recent downloads rather than three
- Larger buttons for canceling and restarting downloads

Developer:
- Enabled CSS Grid Layout, opening up a world of new possibilities for graphic design
- Improved security for screen sharing, which now shows a preview and no longer requires a whitelisted domain
- Redesigned Responsive Design Mode to include device selection, network throttling, and more
