Main new features of Firefox 81
In this new version of the browser a new interface is proposed to preview before printing, which excels at opening in the current tab and replacing existing content (the previous preview interface led to the opening of a new window).
Tools for adjusting page layout and print settings have been moved from the top panel to the right, which also includes additional options like controlling whether headers and backgrounds are printed, and the ability to select a printer.
The integrated PDF document viewer interface has been modernized (icons have been replaced, a light background used for the toolbar). Added support for the AcroForm mechanism to fill in input forms and save the resulting PDF with user input data.
Additionally, the ability to pause audio and video playback was provided. in Firefox using special multimedia buttons on the keyboard or audio headphones without mouse clicks. Playback can also be controlled by sending commands using the MPRIS protocol and it is activated even if the screen is locked or if another program is active.
In addition to the basic light and dark masks, a new Alpenglow theme has been added with colored buttons, menus and windows.
For mobile devices with Adreno 5xx GPU, with the exception of Adreno 505 and 506, WebRender compositing engine is included, which is written in the Rust language and allows you to significantly increase the rendering speed and reduce the CPU load due to outsourcing the rendering operations of the page content to the GPU side, which are implemented via shaders run on the GPU.
