WebRender continues to be released
WebRender is a 2D browser performance system that uses a user's graphics card to deliver a webpage instead of a CPU.
Mozilla has launched WebRender on Firefox 67 in a limited group of users.
With Firefox 77, WebRender is now available by default on all Windows 10 laptops using NVIDIA GPUs (3440 × 1440).
This page opens in its own tab and requires you to enter one certificate hash as an argument to see her information, as shown below.
With Firefox 77, Mozilla has updated the about: Certificate page to allow you to use it without specifying a specific certificate.
