The latest Firefox version, released by Mozilla on January 29, is 65.0. The new version includes fixes for seven security vulnerabilities, as well as some security-related improvements and new features.

Firefox 65 makes it even easier to detect and control the tracking a web site is doing. At the far left end of the address bar, click the small ‘i’ with a circle around it. This will show the site information window. The new Content Blocking section in this window allows you to see the cookies and trackers being used by a site. There’s also a shortcut to the Content Blocking settings, where you can set global preferences for blocking: Strict, Standard, or Custom.

Firefox 65.0 adds support for a video compression technology called AV1, which is expected to provide improvements in video streaming performance for 64-bit Firefox users.

Depending on how you’ve configured Firefox’s update settings, it may prompt you to install the new version. If it doesn’t, try navigating Firefox’s menu (that ‘hamburger’ icon) to Help > About Firefox. You’ll be able to see the current version and update it from there if a new version is available.
