What’s new in Firefox 91 for desktop and Android platforms
Firefox is one of the few browsers that has its own rendering engine, as Opera, Brave, Edge, and others now use Google’s Chromium engine. However, Mozilla doesn’t have much trouble staying competitive with other browsers, as Firefox is about as fast as Chrome and Edge in the real world. Firefox 90 arrived last month with new rendering features and the ability to save credit card information, and now Firefox 91 is starting to roll out.
Firefox 91 on the desktop updates Full Browser Cookie Protection, which confines cookies to the site where they were created, with fixes for various data leaks and other improvements. Mozilla also flipped the switch to HTTPS by default, which attempts to load all content over HTTPS unless it fails (it will then try again over unsecured HTTP). Google began testing a similar feature for Chrome in June.
