Firefox 69 is out, here’s what’s new

Mozilla is releasing a new version of their popular Firefox browser to the stable branch. Firefox 69 includes improvements made to performance, content blocking, and tracking protection. Also, the browser changes the behavior for Flash.

Firefox 69 is yet another release of the Quantum engine-powered browser. Since 2017, Firefox has the Quantum engine which comes with a refined user interface, codenamed "Photon". The browser doesn't include support for XUL-based add-ons any more, so all of the classic add-ons are deprecated and incompatible. See

Thanks to the changes made to the engine and the UI, the browser is amazingly fast. The user interface of Firefox became more responsive and it also starts up noticeably faster. The engine renders web pages much faster than it ever did in the Gecko era.

The key changes in Firefox 69 are as follows:

  • Enhanced Content Blocking which is enabled by default.
  • Enhanced Autoplay Blocking.
  • Flash Player's option Always Activate is now removed.
  • Performance improvements on Windows

Content Blocking/Tracking Protection

Firefox 69 Content Blocking Options

Firefox 69 includes the Enhanced Tracking Protection options under  Preferences > Privacy & Secutiry. There, the user can choose Standard, Strict and Custom mode. In version 69, it is enabled by default, so the browser blocks known trackers, third-party tracking cookies and cryptomining scripts.

Enhanced Autoplay Blocking

Firefox 69 includes advanced options to block media that starts playing automatically. You can find them under Settings > Privacy & Security > Permissions > Autoplay. The default policy can be set for all sites, and whitelist or blacklist individual web sites.
