What’s in the latest Firefox update? Firefox 72 nixes fingerprinting, obnoxious notification appeals





Mozilla on Tuesday launched Firefox 72, which expanded picture-in-picture video mode to macOS and by default blocked “fingerprinting,” an advanced tracking method practiced by some sites and advertisers.

The open-source developers also patched 11 vulnerabilities, five labeled “High,” Mozilla’s second-most-serious threat rating. As usual, some of the flaws might be used by criminals. “We presume that with enough effort … it could be exploited to run arbitrary code,” the firm wrote of the CVE-2019-17017 vulnerability.

Firefox 72 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.

Mozilla now refreshes Firefox every five weeks; it last upgraded the browser on Dec. 3.

(In September 2019, Mozilla said it would reduce the intervals between upgrades. The earlier six-week stretch was shortened to five weeks between Firefox 71 and 72. Starting with March’s Firefox 74, the interval will drop to four weeks.)

PiP-pin for McIntosh?

A month ago, Mozilla introduced Picture-in-Picture (PiP) with Firefox 71, touting the new feature’s ability to display video in a separate, small window while the user continues to surf elsewhere or even works outside the browser. Then, PiP was limited to Firefox running on Windows.
