What’s in the latest Firefox upgrade? Firefox 78 starts ESR transition for enterprises
Mozilla last week upgraded Firefox to version 78, patching a baker’s dozen of security flaws and starting the annual process of retiring last year’s Extended Support Release (ESR) and offering customers the latest enterprise-designed build.
Company engineers patched 13 vulnerabilities, seven labeled “High,” Firefox’s second-most-serious label. Unlike most Firefox refreshes, version 78 did not fix any bugs marked “Critical.”
Firefox 78 can be downloaded for Windows, macOS and Linux from Mozilla’s site. Because Firefox updates in the background, most users can simply 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 describes the refresh process.
