How does Firefox Focus work?


Firefox Focus brings added privacy by allowing you to block known website trackers by category:

  • Ads, analytics and social trackers
  • Other content trackers – this category includes embedded videos, photo slideshows, and news article embeds that could track you. Blocking other content trackers may cause many sites to stop functioning properly.
For Tracking Protection, Firefox Focus uses a list provided by Disconnect to identify and block trackers. You can read more about tracking and the standards Disconnect uses to create its list here.


Firefox Focus works by blocking some parts of web pages from loading. With less to download, web pages often load faster with Firefox Focus. Your mobile data usage may also be lower.

  • Web fonts - fonts that are downloaded from the server (may slow down web pages). Web fonts are typefaces used to style the text on some web pages. Blocking Web fonts will alter the appearance of text on any pages where Web fonts are used, but all text will still display legibly.
