What's in the latest Firefox update? More anti-tracking and money-making (for Mozilla) searches
Mozilla released Firefox 63 for Windows, macOS and Linux, boosting its anti-ad tracking defense by offering an option that blocks cookies from third-party trackers.
Engineers also patched 14 vulnerabilities in Firefox. Just two of them were marked "Critical," Mozilla's highest threat ranking; three others were tagged "High," the next rank down.
Firefox 63, which can be downloaded here, updates in the background, so most users need only relaunch the browser to get the latest version. To manually update, 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." The resulting page shows that the browser is either up to date or details the updating process.
