Mozilla last week refreshed Firefox to version 81, adding a new standard theme for the browser, improving its PDF skills and automatically filing in credit card information.
Engineers also patched six vulnerabilities, half of them labeled “High,” Firefox’s second-most-serious label. Unlike many Firefox upgrades, version 81 did not fix any bugs marked “Critical.”
Firefox 81 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 describes the refresh process.
