All Videos Are Slowed

I-Firefox Audio and Video

Hello, I hope you are well.

All videos played on my FireFox browser are slowed. This happens on any video playing, including on YouTube, even when the video is on 1x speed and is not slowed. It has been getting progressively slower over the past months, and was not fixed after I uninstalled and reinstalled FireFox. Please kindly assist.

Hardware Acceleration: If this setting is misconfigured or your graphics driver is outdated, Firefox will use your CPU instead of your GPU to render the video, causing choppy playback and high system strain. Extension Conflicts: Certain privacy or script-blocking extensions can conflict with YouTube's code, causing the page to lag heavily or freeze.

Try in-private browsing see if that helps.
