Mozilla has released Firefox 63, which introduces Enhanced Tracking Protection, a feature that blocks third-party trackers to increase your privacy online. Mozilla has been focused on data and privacy in recent months, announcing upcoming features like having Firefox block ad-tracking software by default and partnering with ProtonVPN to sell subscriptions to a small group of Firefox users.

For now, Firefox 63 has Enhanced Tracking Protection off by default, but it gives users the option to block third-party tracking cookies or block all trackers. Users can also create exceptions for sites they trust, in case they break due to having trackers blocked. In a detailed blog post discussing this feature, the company explains finding the right trade-offs between having stronger privacy protections and inadvertently hurting small websites that use third-party tools.

Apple’s Safari was the first browser to block third-party cookies by default, and the company also introduced an Intelligent Tracking Prevention feature in 2017 that reduced apps’ abilities to track users across websites.

Today’s Firefox update also includes an update to the New Tab page, which pins users’ top sites. Additionally, Siri Shortcuts is now available for Firefox on iOS, which lets users open a new tab via voice commands. Finally, the new browser will now adapt to match the dark or light theme you’re using in your Windows settings. You can download the latest version here.
