Mozilla has extended its protection of cross-site tracking for all Firefox users who access the web through a private browsing window. This change comes from a security feature called Total Cookie Protection, which is enabled by default on Firefox 89 (the latest version). Mozilla claims that its comprehensive cookie protection is based on a principle that restricts the Firefox browser from sharing Web cookies between websites and saves them in different “cookie jars” to help protect user identities to a certain extent.

Comprehensive cookie protection was first provided to users who enabled the strict Enhanced Tracking Protection (ETP) mode on Firefox 86 in February. However, Mozilla has now expanded its usability and enabled it by default for all users on Firefox 89.

By enabling full cookie protection by default, Mozilla stated in a blog post that each website you visit in a private browsing window will get a separate cookie jar, and Firefox will only keep cookies to that site. This is different from the traditional method of web browsers that allow websites to share cookies.

“Comprehensive cookie protection covers not only cookies, but also various browser technologies that have previously been used for cross-site tracking,” said the non-profit organization.

However, there are some exceptions. Mozilla stated that the new feature does allow cookies to be shared between websites when cross-site login and any similar cross-site functionality is required.

You do not need to perform any specific operations to obtain a new security environment, all you need to do is switch to the private browsing window to achieve comprehensive cookie protection.You can do this by clicking the application menu button and then selecting New private window Options.Or you can press control+ Transfer + phosphorus On a Windows machine or CMD + Transfer + phosphorus Switch to the private browsing window on the Mac computer.

In addition to comprehensive cookie protection, Firefox enables a series of features by default when using private browsing sessions. These include super cookie protection to prevent super cookies from tracking you from one site to another, and SmartBlock to repair web pages that were previously damaged when tracking scripts were blocked.

Browsers in private browsing also block elements from domains in the Disconnect list of known trackers, including cookies, scripts, tracking pixels, and other resources. Once the private browsing session ends, it will also restrict fingerprint scripts and clear cookies and cache.

In addition to the default protection layer for cross-site cookie sharing, Firefox 89 also brings a redesigned experience, bringing a cleaner Web browsing experience. It has independent tabs and simpler navigation. The updated browser can be downloaded on the desktop.
