Reverted Third-party cookies are blocked by default

Published: | Categories: Networking, Privacy & Security


Starting with Firefox 22, third-party cookies are blocked by default, like Apple Safari, to give users more control over online privacy. For details, see the post on Mozilla Privacy Blog and Jonathan Mayer’s FAQ about the new Firefox cookie policy.

Update: This change has been postponed to collect and analyze data on the effect of blocking some third-party cookies. In the Beta and Release channels, the default preference will be kept to allow third-party cookies. See Brendan Eich’s blog post for details.

Update 2: Starting with Firefox 65, Third-party tracking cookies are blocked by default.
