- You just click the Firefox button in the top-left corner and choose 'Options...'
- Now, go to the Advanced section at the top and uncheck the box that says 'Use hardware acceleration where available' under the Browsing section.
- Now you're done. I'm not sure about this, but it may require closing and restarting the browser to complete.
