Firefox 88 released with new privacy features

Firefox 88 version has been released, this version is mainly to further strengthen user privacy, prohibiting websites from using the property to track users across websites.

Moreover, the property can set or return a string that stores the name of the window. In the same window, all pages share the same Window. name, which gives many websites the opportunity to spy on user privacy.

In Firefox 88, the browser will automatically clear the property when navigating between websites.

The updated content is as follows:


  • PDF forms now support embedding JavaScript in PDF files, and some PDF forms use JavaScript for verification and other interactive functions.
  • Print update: Margin units are now localized.
  • The Linux version supports smooth pinching and zooming using the touchpad.
  • To prevent cross-site privacy leaks, Firefox now isolates the data to the website that created the data.


  • Screen readers no longer mistakenly read the visually hidden content of the website, such as articles in the Google Help panel.
  • Various security fixes.


  • If the user has granted access to the same device in the same tab of the same website in the past 50 seconds, Firefox will not prompt the user to access the microphone or camera. This reduces the number of times users are prompted to grant access to the device.
  • Removed the “Take a Screenshot” function from the page operation menu in the Url bar. To take a screenshot, right-click to open the context menu. You can also add screenshot shortcuts directly on the toolbar through the custom menu. Open the Firefox menu and select “Customize…”.
  • FTP has been disabled and is planned to be completely removed in an upcoming version.


  • A new switch button has been added to the network panel to switch between the HTTP response in JSON format and the original data.
