Firefox 69.0 Changes

Flash Player cannot be activated permanently anymore on sites

Mozilla removed the “always activate” option for Flash Player content on the Internet. While it is still possible to play Flash content using Firefox, it is no longer possible to configure Firefox to load Flash content automatically on specific sites going forward.

Firefox won’t support the “remember this decision” option anymore when it comes to Flash content.

Firefox will drop support for Flash at the end of 2020 just like Google Chrome,Microsoft Edge, and many other browsers.

Enhanced Tracking Protection is turned on by default

Firefox 69.0 rolls out with enhanced Tracking Protection functionality. The default setting blocks third-party tracking cookies and cryptomining scripts automatically in that version 69.

The stricter settings block fingerprinting next to that as well.

Enhanced Autoplay Blocking

Firefox’s option to block media from autoplaying received an improvement in Firefox 69.0 as well. The feature blocked autoplaying video only if it played sound previously.

Mozilla added new autoplay options to Firefox to block any kind of autoplay instead.

  1. Load about:preferences#privacy in the Firefox address bar.
  2. Scroll down to the Permissions section on the page.
  3. There you find the new Autoplay setting. Activate Settings next to it to open the configuration menu.
  4. You can set the default for all websites at the top. The default is block audio but you may change that to “block audio and video”, or “allow audio and video”. Note that this affects autoplay only.

Changes to the loading of userChrome.css and userContent.css

Firefox does not load userChrome.css or userContent.css anymore by default. Firefox users who use these customization files need to change a preference in the browser to restore the functionality.

  1. Load about:config in the Firefox address bar.
  2. Confirm that you will be careful.
  3. Search for toolkit.legacyUserProfileCustomizations.stylesheets.
  4. Set the value to True.
