New features and improvements
Performance Improvements, less memory usage
The headline feature for this release is improvements on performance and memory management, with Mozilla noting that Firefox 83.0 gets an improvement of 15% improvement in page loads, page responsiveness by 12% and memory usage reduced by up to 8%.
New HTTPS-Only Mode
Firefox 83.0 introduces a new HTTPS-Only mode — previously available by installing an extension — forcing all connections to go through by https. Any requests that cannot go through displays a security warning.
The feature is disabled by default but can be enabled by using a simple flag:
- Load about:preferences#privacy in the browser’s address bar.
- Scroll down to the new HTTPS-Only Mode section on the page
- Switch from “Don’t enable HTTPS Only Mode” to either “Enable HTTPS-Only Mode in all windows” or “Enable HTTPS-Only Mode in private windows only”.
