What's in the latest Firefox upgrade? Firefox 79 adds under-the-hood improvements, but no pizzaz
Mozilla this week upgraded Firefox to version 79, patching 10 vulnerabilities without making any notable changes that users will see.
Of the 10 security bugs, Mozilla marked four as "High," the browser's second-most-serious label.
Firefox 79 can be downloaded for Windows, macOS and Linux from Mozilla's site. Because Firefox updates in the background, most users will get the latest version just by relaunching the browser. 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 in-process refresh.
