Content blocking is a collection of Firefox privacy features that protect you from threats and annoyances on the Web. This includes protections against trackers, which collect your browsing data across multiple websites. Starting with Firefox version 67, you can block harmful scripts including cryptominers and fingerprinters. These privacy protections are mostly invisible, but youâll know theyâre working when you see a shield icon on the left within your address bar.
Starting with Firefox 69, Enhanced Tracking Protection for content blocking will automatically be turned on by default for all users worldwide as part of the âStandardâ setting in the Firefox browser and will block known âthird-party tracking cookiesâ according to the Disconnect list.
In some cases, blocking this content makes pages load faster, but can affect the page’s functionality such as prevent pages or parts of pages from loading. If content blocking interferes with your browsing, you can disable it on individual sites.
Since Private Browsing doesnât save information about your browsing session, when you disable content blocking for a site, it will only remain disabled during your current private browsing session. When you start a new private browsing session, your content blocking settings will be restored for all sites. If youâve disabled content blocking for a site while in a normal browsing window, Firefox will continue to disable content blocking for this same site when in a private window.
This tutorial will show you how to turn on or off content blocking for individual sites in Mozilla Firefox.
