Firefox 83 Brings HTTPS-Only Mode And Performance Improvements

Firefox version 83 include an HTTPS-Only mode, Picture-in-Picture, and the long-awaited pinch zooming feature.

Work on Firefox’s performance and memory usage continued. As a result, Mozilla notes that Firefox 83 page load performance has improved by up to 15%, page responsiveness by up to 12%, and memory usage has been reduced by up to 8%.

Firefox 83 includes an option to accept only HTTPS connections when the new HTTPS-Only Mode is enabled. The browser attempts to upgrade any non-HTTPS connection in the process, and displays a warning screen if the site cannot be loaded at all. Firefox users may then continue to the HTTP site anyway or cancel the operation.

The feature is disabled by default. To enable HTTPS-Only mode in Firefox 83, go to Options > Privacy & Security, click on Enable HTTPS-Only Mode in all windows.

Picture-in-Picture now supports keyboard shortcuts for fast forwarding and rewinding videos. Use the arrow keys to move forward and back 15 seconds, along with volume controls.

PDF Viewer feature is available since 81. In addition to, in Firefox 83, you will see fresh look and support to fill in, print and save PDF.

There are several other improvements and fixes to Firefox including searching through bookmarks, open tabs, and history from the bottom of the search panel.
