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.

Microsoft on Monday released Exchange 2019, the newest version of its venerable email server. But with Windows Server 2019 still in software purgatory, customers were unable to deploy or even test the on-premises, perpetual-license software.

"We're pleased to announce the final build of Exchange Server 2019 is now available and can be downloaded from the Volume Licensing Service Center," Microsoft announced in a blog post.
