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.
Some recent graphics driver versions are made available as an optional update from the Windows Update feature. If you haven't set Windows to automatically install recommended updates, follow these steps:
Windows Vista: The View available updates panel will open. Click "Optional".
Windows 7: The Select updates you want to install panel will open.
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 Start 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:
If you don't know which graphics card you have, look in the graphics section of Firefox's about:support Troubleshooting Information page.
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.
In the address bar, type about:config and press EnterReturn.
