Facebook trackers remained blocked by default in strict mode and private windows, but if a user wants to login using Facebook then SmartBlock 2.0 will lower its shields.
Firefox 90 appeared from Mozilla this week, and one of the new features that arrived was better support for logging in using Facebook credentials when the browser is in strict tracker blocking mode, or a private window. SmartBlock first appeared in Firefox 87, released in March, and it provided local stand-ins for blocked third-party tracking scripts. „These stand-in scripts behave just enough like the original ones to make sure that the website works properly. They allow broken sites relying on the original scripts to load with their functionality intact,“ Mozilla said at the time. One area where SmartBlock failed though, was supporting Facebook login buttons across the web. In a blog post, Mozilla explained it was due to Facebook trackers being included on the list of tracker provided by its partner, but the updated SmartBlock 2.0 should fix this. „Prior to Firefox 90, if you were using a private browsing window, when you clicked on the ‚Continue with Facebook‘ button to sign in, the ’sign in‘ would fail to proceed because the third-party Facebook script required had been blocked by Firefox,“ the blog states.
