The latest Firefox includes fixes for at least twenty security vulnerabilities, and improves overall privacy and security by enabling Enhanced Tracking Protection by default.
When enabled, Firefox’s Enhanced Tracking Protection reduces your exposure to the information-gathering efforts that otherwise silently occur when you browse. It also provides protection against cryptominers, which surrepticiously use a portion of your computer’s resources to make money for someone else.
New in Firefox 69.0 is a feature that allows you to block any video you encounter, not just those with autoplayed audio: Block Autoplay.
The ‘Always Activate’ option for Flash content has been removed. Firefox now asks for permission before it will play any Flash content.
Default installations of Firefox will usually update themselves, but if you’re not sure what version you’re running, click the browser’s ‘hamburger’ menu button at the top right, then navigate to Help
