What’s in the latest Firefox upgrade? Proliferating picture-in-picture, even more anti-tracking
Mozilla last week raised the Firefox version count to 86, adding multiple picture-in-picture video viewing and bolstering the browser’s anti-tracking defenses by isolating all cookies in the sites that create them.
Security engineers also patched 12 vulnerabilities, five of which were pegged as “High,” Firefox’s second-most-serious label.
Firefox 86 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 or pop-up shows that the browser is either up to date or displays the refresh process.
