How do I Change Buffering for a Video in Mozilla Firefox?

Mozilla Firefox is a popular web browser thanks to its add-on architecture and the ease with which you can modify the open source browser’s settings to improve performance. Changing the online video buffering settings can be useful if you are working on a older computer or if you are accessing the web from a slow Internet connection. With just a few adjustments, you can set Firefox to buffer a greater portion of the video, ensuring that you can view the video without interruption.
