Upgrade your graphics drivers to use hardware acceleration and WebGL

Firefox and some plugins use your graphics card to help speed up the display of web content. Graphic cards are also used by advanced web features like WebGL. To fix problems with these features or to take advantage of them, you may need to update your graphics card drivers. This article describes how to do that.

6. If you find some, check the latest one and click "Review and install updates".
7. Click Install Updates.
8. Wait until update is installed. When prompted, restart your computer.

In Windows 10, all drivers are automatically downloaded and installed through Windows Update but you can manually search for an updated graphics driver. See Microsoft's support article, Update drivers in Windows 10 for details. If there are no updates available or if the updates don't solve your problems, continue to the next section.

Some computer manufacturers include a system update tool that updates drivers and bypasses the Windows ones. You may be required to use this tool to update graphics drivers.

Just search for this tool from the menu. Some possible search terms are the name of your computer manufacturer (such as Dell or HP) or generic terms like "update", "maintenance" or "driver". Open the tool and apply all available updates.

If there is no update tool, no updates available, or if the updates don't solve your problems, continue to the next section.

If your distribution's standard update process doesn't give you the latest drivers, you may need to look for other package repositories for your distribution. For example, to upgrade closed-source drivers on Ubuntu, you may need to go to System Settings > Hardware > Additional Drivers.

You can also install a generic graphics driver from your graphics card manufacturer's website. These are usually kept up-to-date and are designed to work on a variety of systems:

• Intel
• AMD/ATI
• NVIDIA

If you don't know which graphics card you have, look in the graphics section of Firefox's about:support Troubleshooting Information page.

Note: Hardware acceleration is not available for graphics cards from other manufacturers.

Note: After downloading the graphics driver, the installation wizard may prevent you from installing it because your current driver is customized by your computer manufacturer.

Warning: With some combinations of computer and graphics card, you may experience problems with generic versions of software drivers.

1. Click the Apple.
2. On the "Apple" menu, click "Software Update."
3. If there is a Mac OS X update available, you can install it. If there is a graphics driver update, it will be included in the Mac OS X update.

Reboot your computer to use the new graphics driver.

Unfortunately, due to the wide range of possible driver, video card and operating system combinations, hardware acceleration or 3D web graphics (WebGL) may still not work for you in Firefox. In these instances you fix the problems by disabling hardware acceleration and WebGL.
