With Firefox 72, Mozilla focuses primarily on ensuring the privacy of browser users. The most important feature that the update brings is the standard blocking of fingerprint scripts that collect data without permission.

At the end of last year, Mozilla already announced that it wants to prohibit such fingerprint scripts, as they (unlike cookies) do not need to ask permission from users. As part of the Enhanced Tracking Protection feature, Firefox 72 introduces the default blocking of such scripts.

The data collected is limited to certain elements of the user’s computer, such as the screen resolution, the browser used, how many cores the system’s CPU has and which language is set as default.

Pop-up notifications also blocked

In addition to improving user privacy, Firefox 72 also introduces an option to better manage notifications of websites. Previously, it was possible to completely block such notifications, but now users will no longer receive a notification that opens an extra screen. Instead, a small text balloon will appear in the address bar itself, allowing users to set their preferences.

In addition to features for improved security and a better user experience, Firefox 72 also adds an option for Linux and Mac users that was already available on Windows. The so-called picture-in-picture mode, in which a small window with a playing video remains visible in the foreground as the user continues browsing, is now also available on Mac and Linux.

Finally, with Firefox 72, Mozilla also complies with the California Consumer Privacy Act, which has been in force in the American state of California since the beginning of this year. This gives people the right to request the deletion of all collected data by a company. As a result, Mozilla also offers this option directly to all Firefox users who do not live in that state.
