Mozilla on Tuesday upgraded Firefox to version 84, adding native support for Apple’s new ARM-based Macs and declaring the browser the last to support Adobe’s Flash Player.
Security engineers also patched 14 vulnerabilities, one pegged “Critical,” Firefox’s most-serious label. Six other flaws were marked “High,” the next lower threat level.
Firefox 84 can be downloaded for Windows, macOS and Linux from Mozilla’s site. Because Firefox updates in the background, most users can just 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.
