Firefox turned on full cookie protection by default

Firefox Developers reportedthat from June 14, the Total Cookie Protection feature will be enabled in the default browser for all users.

This feature restricts cookies to the site they were created on, thus preventing trackers from use them to track user activity on other online resources and collect personal data.

Total Cookie Protection creates a separate cookie for each website you visit - each goes into its own isolated "jar". Sites cannot access "banks" that do not belong to them and learn what another site knows about the user.

Total Cookie Protection gives you freedom from aggressive advertising and reduces the amount of information that companies collect about you, the developers added. The feature is already available in the browser on Windows, Linux and Mac. Firefox mobile browsers do not yet support it.
