Enabling Mozilla Firefox to support the EGL API for hardware graphics acceleration

Linux, firefox

EGL allows you to dramatically increase the FPS frame rate in web games and speed up the processing of 3D and 2D graphics and video.

EGLEGL is a cross-platform API developed by Khronos. EGL communicates via MESA and OpenGL with the native Linux graphics card driver for X11. Data when using EGL is written directly to the frame buffer of the video card, which reduces the load on the central processor.
EGL is implemented not only in X11, but also in Windows and Android.

Why doesn't EGL work by default in the Mozilla Firefox web browser on an nVidia and ATI or AMD video card?

EGL disabled for video cards Nvidia entry level that have nVidia version driver below 470.82.0.0.
See list of supported products for Linux Nvidia 470 driver.
Also EGL does not work with the free Nouveau driver (see below).Firefox source text - GfxInfo.cpp).
All ATI video cards are blocked.
AMD- the situation is better. The RadeonSI Gallium3D driver is actively being developed, which is suitable for video cards starting with the Radeon HD 7000 "Southern Islands" series (see the list of video cards below).

Is it possible to enable EGL acceleration in Firefox on an nVidia video card without buying a new one?

First, install the branded video card driver.

Secondly, you about:config

Set new values for the parameters:
*gfx.webrender.all=>true*
layers.acceleration.force-enabled=>true
layers.gpu-process.enabled=>true
layers.gpu-process.force-enabled=>true**
*gfx.x11-egl.force-enabled=>true

The last parameter "gfx.x11-egl.force-enabled" is responsible for forcing EGL to be enabled, even if the old video card is in the Firefox "black list".
You can also enable EGL via an environment variable when launching Firefox from the command line.

MOZ_X11_EGL=1 LIBVA_DRIVER_NAME=nvidia firefox

Where LIBVA_DRIVER_NAME=nvidia with an AMD video card is replaced by LIBVA_DRIVER_NAME=radeonsi

For Intel integrated video cards,depending on generation, parameter LIBVA_DRIVER_NAME может принимать значения i965 или iHD или Xe.

After changing the settings in about:config, you need to restart the Firefox web browser.
To cancel settings, either create a new Firefox profile, or edit

What does high CPU usage mean for the GPU Process?

There may be several reasons:

Insufficient OpenGL performance on an entry-level video card.
Mesa 3D version is outdated and does not contain libEGL, libGL, libGLESv1_CM, libGLESv2 libraries.
Outdated video card driver (lower than Nvidia 470.82 or AMD lower than 25.20.3).
Unsupported operating system (AMD for its video cards recommends ubuntu 22.04.5 HWE, Ubuntu 24.04.3, RHEL 10.0, RHEL 9.6, SLED/SLES 15 SP7).

Checking WebGL functionality in Mozilla Firefox

You can see if EGL is enabled in about:support- lines mentioning EGL and the parameter value:
*X11_EGL- default available, and if "env blocklisted Blocklisted by gfxInfo" is disabled, the forced inclusion of "user force_enabled" is available.

Checking the functioning of the EGL:
*WebGL aquarium[/mark]
