Digital Privacy: Mozilla Launches Redesigned Controls for the Content Blocking Section in Firefox

From the Mozilla Blog:

One of the features we outlined in our approach to anti-tracking was Enhanced Tracking Protection, otherwise known as “removing cross-site tracking”. We initially announced in October that we would roll out Enhanced Tracking Protection off-by-default. This was just one of the many steps we took to help prepare users when we turn this on by default this year. We continue to experiment and share our journey to ensure we balance these new preferences with the experiences our users want and expect. Before we roll this feature out by default, we plan to run a few more experiments and users can expect to hear more from us about it.

As a result of some of our previous testing, we’re happy to announce a new set of redesigned controls for the Content Blocking section in today’s Firefox release where users can choose their desired level of privacy protection.


Additional features in today’s Firefox release include:

  • AV1 Support – For Windows users, Firefox now supports the royalty-free video compression technology, AV1. Mozilla has contributed to this new open standard which keep high-quality video affordable for everyone. It can open up business opportunities, and remove barriers to entry for entrepreneurs, artists, and regular people.
  • Updated Performance Management – For anyone who likes to look under the hood and find out why a specific web page is taking too long to load, you can check our revamped Task Manager page when you type about:performance in the address bar. It reports memory usage for tabs and add-ons. From there you can see what (tab, ads in tabs, extension, etc) could be the possible cause, and find a solution either by refreshing/closing the tab, blocking tab, or uninstall the extension.
