Browser Mozilla Firefox released an update last week. It includes such an important change as blocking Third party cookies and trackers default.
This update also affects trackers Google Analyitcs, Facebook Pixel and possibly Yandex Metrica. This was followed by a wave of discontent on Twitter from webmasters and SEO specialists:
Now you re coercing everyone with Firefox to immediately block Google Analytics, Facebook Pixel, and more, taking data that small businesses and developers rely on.
Which was answered by Mozilla Firefox developer Asa Dotzlerwhere he argues that the change should provide better user privacy:
Are you claiming that we are taking someone s data? I claim that this is user data, and the user has the right to maintain their confidentiality. If a user wants to share his traffic data with the site, he can disable tracking protection in the settings.
Recall that earlier this blocking feature was in the advanced browser settings, but it was not by default.
Now, to change the settings, you need to move the marker to the Personal (Custom) mode.
