Firefox 70 for Mac Brings Social Tracking Protection and Notable Performance Gains

Mozilla has launched Firefox 70 for macOS, which continues to enhance the browser's privacy features as well as bringing significant improvements to performance and power efficiency.

Recent versions of Firefox have included several extensions to the Mozilla's Enhanced Tracking Protection (ETP) system, and this release is no different. ETP now features social tracking protection, which blocks cross-site tracking cookies from sites like Facebook, Twitter, and LinkedIn.

Firefox 70 also introduces a Privacy Protections report, which offers a summary of the trackers Firefox has blocked. So if you think the blocking is too strict (if a website doesn't work properly, for example) you can check the report and customize the protection accordingly.

In addition, there are improvements to Firefox Lockwise, the browser's digital identity and password management tool. Lockwise now lets you create, update, and delete logins and passwords to sync across all your devices. Meanwhile, integrated breach alerts from Firefox Monitor notify you if saved logins and passwords have been compromised in online data breaches, and Monitor is also now capable of complex password generation.

Thanks to improvements to the browser's core engine components, Firefox 70 users can also expect a significant reduction in power consumption (Mozilla quote improved power usage by three times or more for many use cases), along with faster page loads by as much as 22 percent, and reduced resource use for video by up to 37 percent.

Mozilla's full changelog can be found here. If you're already a Firefox user, you should receive an automatic upgrade after restarting the browser. For everyone else, Firefox 70 is available for macOS as a free download directly from the Mozilla website.
