Mozilla plans to launch several improvements to the PDF reader of the organization's Firefox web browser when the browser hits version 81 later this year. Besides design changes that bring the interface closer to the Photo-style of Firefox, it is form filling and support for layers that Firefox users can look forward to.
Firefox 81 will be released on September 22, 2020 according to the Firefox release schedule.
The Photon design implementation changes several interface elements of the native Firefox PDF viewer. Icons are now flat and the larger buttons are designed to improve control opens on touch-capable devices.
