For the past couple of days, YouTube videos have been choppy. The sound isn't a problem, it's just the image that stutters every few seconds. It doesn't happen on other platforms, nor if I try to view the video in another browser. I've tried to fix it by updating both the latest version of Firefox and all Windows updates and graphics card drivers, but it hasn't worked. I decided to uninstall and reinstall Firefox, and although the problem seemed to be resolved for a while, the videos continue to display stutteringly. I need some advice on how to fix this, as it must be a configuration issue, and I want to continue using Firefox as my browser.
