Mozilla this week upgraded Firefox to version 83, adding an “HTTPS-Only Mode” that tries to connect to all websites through the more secure HTTPS protocol and, after failing to do so, warning users of with a can’t-miss-it, in-your-face alert.
Company engineers also patched 21 vulnerabilities, four marked “High,” Firefox’s second-most-serious label. Firefox 83 did not include fixes for any bugs marked “Critical.”
Firefox 83 can be downloaded for Windows, macOS and Linux from Mozilla’s site. Because Firefox updates in the background, most users need only relaunch the browser to get the latest version. To manually update on Windows, pull up the menu under the three horizontal bars at the upper right, then click the help icon (the question mark within a circle). Choose “About Firefox.” (On macOS, “About Firefox” can be found under the “Firefox” menu.) The resulting page shows that the browser is either up to date or displays the refresh process.
