Mozilla has introduced SmartBlock 2.0, the next version of its intelligent cross-site tracking blocking tech, with the release of Firefox 90.
The SmartBlock mechanism, introduced with Firefox 87 in March, works to ensure that the Tracking Protection feature and Strict Mode will not break websites when blocking tracking scripts.
"Third-party Facebook scripts are blocked to prevent you from being tracked, but are now automatically loaded"just in time" if you decide to "Log in with Facebook" on any website," Mozilla added.
Mozilla also announced in June that Total Cookie Protection is enabled by default in Private Browsing windows starting with Firefox 89 to automatically protect users from cross-site tracking.
Today's Firefox release also adds support for background auto-updates while the web browser is not running.
The "Open Image in New Tab" context menu item now opens images and media in a background tab by default.
